Predictive Algorithm for Churn analysis

Hi,
Can anybody help me with the algorithm which I can use for churn analysis?
Thanks,
Atul

Hi Atul,
For Churn analysis or what is usually referred to as a binary classification problem where the customer is either staying or leaving=churning I would suggest one of the following algorithms:
CNR Decision Tree - which also provides a decision tree to explain which feature split is influencing the target (churn) the most.
You could also chose one of the R based Neural Network algorithms, however the produced predictive model & results are usually hard to explain.
If need be you can enhance the number of available algorithms by adding you own R functions - there are a lot of examples in this community.
If you have SAP HANA you could also chose:
Decision Trees:C4.5, CHAID or CART (new in SAP HANA SP08).
Other supervised learning algorithms for binary classification: Naive Bayes or SVM (Support Vector Machine).
There are a lot more but this should get you started.
Best regards,
Kurt Holst

I am looking for Modal Analysis Labview VI lib or example?

I am looking for Modal Analysis Labview VI lib? specifically, I conducted Frequency Response Measurements, I managed to construct the experimental frequency response function. Now, I am looking for modal extraction from the experimentally determined frequency response function.
I appreciate if someone knows about Labview VI or example to perform the curve fitting in the frequency domain to extract the modal parameters.
Thank you in advance.

Atef,
I found the following paragraph in the on-line description of the Advanced Signal Processing Toolset for LabVIEW:
<>
"You can also construct your own custom applications in LabVIEW with a VI library of the most efficient and common algorithms such as covariance, principle component auto-regression (PCAR), Prony's method, and the matrix-pencil method. Some of these methods have not been commercially available before the release of this toolset. Using these VIs, you can perform both super-resolution analysis and modal-analysis. Moreover, VIs provided can easily be tailored for many other signal analysis applications, such as system identification and linear prediction."
It seems as if this set of tools might
help you with your application.
I hope this suggestion gets you pointed in the right direction. Have a pleasant weekend.

Predictive Analytics for Equipment Maintenance?

Could an equipment failure or parts shortage be predicted based on an analysis of work orders, parts and equipment usage? Predictive Analytics uses several techniques from data mining and statistics to process data in order to predict future trends and behavior patterns. A key characteristic of the analysis is to provide insight into equipment failure and parts usage that may not be readily apparent through simple reporting. Predictive analytics is an option of Oracle's Relational Database (9.1, 9.2, 10.1, 10.2, and 11.1). If you have been using Oracle eAM for over one year and would like to participate in a proof of concept (working closely with the Product Strategy team) to determine the potential benefits of predictive analytics please contact me. You can explore data mining and predictive analytics at www.oracle.com/technology/products/bi/odm/index.html.

Hi,
We are in our 2nd year of eAM Implementation and I'm very keen to explore the full functionality of this module.
Yes, I would like to participate in a proof of concept (working closely with the Product Strategy team) to determine the potential benefits of predictive analytics Please initiate contact.

Try the latest Fixpack which is 13. This will take WebSphere to 6.1.0.13
Every fixpack from IBM for WebSphere now come with its own UpdateInstaller, downloaded separately. Install this first.
Then copy the Fixpack .pak file into the /maintenance folder of the UpdateInstaller. Then run the UpdateInstaller.
Also, remember that the fixpack for the IBM Java SDK also needs to be separately downloaded and installed.

Calculationg current and past year for a Analysis report in obiee 11.5

Dear All,
Need some help here.
I am a beginner in OBIEE and need some help to build a report in obiee 11.5 as described below;
I need to create a PnL report such that I show current years profit and loss AND prior year profit and loss figures in a report side by side for comparitive analysis for user.
My data is an essbase database, and have a years dimension with values 'current year' , 'F08', and 'Prior Year'. and other measurs such as revenue, % revenue, gross profit, cost of sales, operating expenses etc. (I am using 107 from oracle downloads) for obiee 11.5
There is another dimesion called time period with members as Q1, Q2, Q3, and Q4, and each having respective months (e.g. Jan, Feb, Mar for Q1 etc)
I also have a scenario dimension with members as Actual, plan, Forecast, Wht -if..
Now I need to create a this report.
I created this report based on approch no 1 below;
Appraoch 1
- Create two analysis reports with all the above columns.
- specify filter for year column equal to current year for first report
- specify filter for year column equal to prior year for second report
- create a dashboard with a promt (radio button) based on column scenario
- create two sections placed side by side below the promt and place above two reports in those two sections so that they appear side by side
Nw when I run this dashboard, it works fine, and shows me the current and prior data for actual, plan etc...
BUT....
I need to create the same reports using a single analysis report instead of two separate reports with hardcoded values for year filter.
Now I tried use AGO funtions on but , it requires a column with numerical value so that it can calculate the past year, but in my case year is a column hving text value and hence i cant use it.
I would like to know how to build such a report using any other variable or function or any rpd level modifitions.
If I had a year dimesion with numeric values, then how would I use to calculate the past year once u select current year .?
Let say values are 2012, 2011, 2010 etc. so If I select 2012 as current year, I should get data for 2012, and 2011, if I select 2011, then I should get data for 2011 ,and 2010.
Please help me to build logic either at analysis level or at repository level
Thanks and Regards
Santosh

Hi,
As per I understand your requirement,
In Pivot table, place 'Year' in pivot columns instead of rows.
Create an SQL filter on Year and put the condition as:
*"Year" BETWEEN @{Presentation_Variable} - 1 AND @{Presentation_Variable}*
You will get the result for selected year and the previous year.
Hope it helps..

Hi Sam
As I said, you can tag variance of FG upto some extent to the COGS of FG...
Also note that, w/o ML, variance is disposed off in the month of mfg, where as COGS comes in the month of sale... For eg: You mfr 100 Kgs @ Actual cost of 120, where as your std cost is 100... You sell 50 kgs in Month 1 and 50 kg in month 2
In Month 1
COGS = 50 (@ std cost)
Variance = 20
In Month 2
COGS = 50
Variance = 0
Variance analysis w/o ML is always limited.. At best what you can do is draw your COPA reports on YTD (Year To Date) basis... Assuming that your closing and opening stock is more or less the same, your variance related to FG can now be analysed with COGS and revenues....
Also, if your prod order for FG is tagged to sale order on account of MTO scenario, your COPA doc for variance will have customer info as well
With ML in place
Variance of SFG can be rolled upto FG... i.e. Say, variance in SFG is 20 USD... Std cost of FG is 125 USD... When you roll up the variance to FG, your FG valuation will become 145 USD....
Also, if part of the FG is sold off, then prorata variance will go to Inventory and the rest can be taken to COGS.. i.e. not only FG, you can also revaluate your COGS with ML...

Differance amoung the Valuation Methods for Result Analysis

Dear All,
In SAP Product Cost Controlling ther are 3 types of Cosings
1. Production Cost by Order
Path:- Production Cost by Order ---> Period end Closing ->WIP->Defind Valuation Method for( Actual Cost)
2. Production Cost By Period
Path:- Production Cost by Period ---> Period end Closing ->WIP->Defind Valuation Method for ( Target Cost )
3. Production Cost by Sales Order
Path :- Production Cost by Sales Order ---> Period end Closing --->Defind Valuation Method for Result Analysis.
Note: Here the point is Valuation Methods ( 1 to 17 ) availabel in Production Cost by Sales Order only. The Valution Method is very important to Calculate WIP. Different Countries follows different methods, but in the By Order and By Period we can get these Valuation Methods. What would be the reasno behind this.

Oracle Financials or Hyperion Planning for variance analysis??

We are considering Hyperion Planning for our Departmental budgets/forecasts and I'm have a disagreement with a few piers. Was hoping you could help. It's my contention that the budgets/forecasts AND actuals should be populated in Hyperion Planning. A few of my piers contend that the budgets/forecats should be housed in Hyperion Planning and pushed down to Oracle Financials for variance analysis - in order to provide drill back capability into the transacations that caused the variance.
Since H.P. is a consolidated system, I would think it's impossible to budget at a summary account level in H.P. and push it to base level/transaction level within Oracle Financials (one to many). In my view, the actuals should flow up from Oracle Financials, via FDM, into H.P. where variance analysis can take place? I would think drill back capability could be provided via FDM within Planning?
Anyway, was hoping to get your thoughts.

Hi,
We are currently in the final phase of implementing Oracle Financials and Hyperion for the same purpose that you have described in your post. We use Oracle Financials to record actuals and then transfer it to Hyperion under the scenario 'Actual'. While the budget/forecast data in only entered/saved in Hyperion. There are several financial reports for variances that are generated out of Hyperion. So far, this arrangement is serving us pretty well. I second your point that in Hyperion, we can easily compare summary level data. We have Hyperion reports that do variances calculations for sub-totals. In fact, we are also using HP reports for consolidated statements such as Balance sheet, Income statement etc. The actual data for these statements is coming from GL.
As for drill through functionality (from HP to sub-ledger details in financials), we are in process of implementing FDM and use it for both (1) loading data and (2) drill through.
Hope this helps.

Time Series Graph Show Inappropriate Data for Continuous Analysis

Hi All,
I have marked Month as the Chronological Key in my BMM Layer but still I am unable to view the data correctly in my Time Series graph because it shows Inappropriate Data for Continuous Analysis at the time of creating the Graph. Can anybody help me out with the same.
Thanks

What data type is your key? The chronological key is required for the time series formulas (ago etc.).
The time series chart requires a date or datetime data type to work - perhaps a new column with the first of the month/period would help? Regards,

How to use EBS R12 Database (10.2.0.2) for report analysis tools?

As Srini states, knowing more about your requirements would help us to help you. :-)
Do you need a daily twice/daily snapshot of your data? If so, then you might be able to implement the solution that Srini mentioned earlier. An added benefit of this method is that it can go beyond the creation of a reporting database: it can also be leveraged in the creation of additional clones for test and dev environments.
Do you need real-time replication of data to your reporting database? If so, then you might want to investigate Oracle Streams/Goldengate (disclaimer: I'm typing on the fly, so I'm not 100% certain that this is supported).
If you're willing to license more Oracle software to solve your problem, you might also consider Oracle Business Intelligence Applications, which has out-of-the-box integration with E-Business Suite for common reporting/business intelligence needs. There are additional costs involved, but you can weigh those against the development costs of "rolling your own" MVs and reports, and maintaining them.
Again, knowing your requirements, constraints, and points of flexibility will go a long way toward figuring out which option best suits you. :)

John P.

Seeing the detailed sql with db table names for an analysis in OBIEE 11g?

Hello All,
I am trying to see the detailed sql for an analysis to see which tables my analysis is hitting back in the database. Currently all i see is the subject area name with bunch of s_0, S_1,S_2.... but i want to see the actual table names which the Analysis is pulling the data from, I am new to OBIEE. Any help or advise with the steps in order to accomplish my goal is greatly appreciated.
Thanks,

Hi ravi,
You can check in the presentation services by going to Administration/manage session/view log for the specific report that you are running.
You can even check the SQL in log file NqQuery.log in your installation folder C:OracleBI\server\log\NqQuery.log
Check this Courtesy by gerard http://gerardnico.com/wiki/dat/obiee/manage_session_log
hope answered.

Load balancing algorithm for groups in RZ12

Hello,
I would like to know the load balancing algorithm for groups defined in RZ12.
I know that log on groups for external connections are administered via SMLG and table RZLLICLASS.
I also know that RFC resources can be managed for RFC logon groups via RZ12.
Kind regards,

Hello!
Found this post while searching information about RFC and Logon Groups...
I have some mess in my head with SMLG functionality and RZ12. As I know SMLG we can use to distribute users to application server instances, it gives us good achievement in performance. With RZ12 we can distribute RFC connection of particular job for parallel execution on predefined application server. With SMQS and SMQR transaction we can set "Name of AS Group" to route RFC-execution on certain server or servers. But I have troubles with understanding. Imagine, we set up group 1 with 2 servers (name it RFC_GR1), and group 2 with another 2 servers (name it RFC_GR2). How could qRFC scheduler decide on which RFC server group (RFC_GR1 or RFC_GR2) distribute RFC-execution? How to interact "Name of AS Group" with RFC groups if we can set only one group? How could we distribute RFC-execution depending on our logon groups (smlg)? We would like to distribute RFC depending on SAP logon groups. Is it possible? Or do I compare apple and orange?
