Need for predictive analysis?

Folks, I have this massive 700,000 sq. ft. facility we need to deploy wireless to using Cisco access points inside the building and also outdoors.
Do you see any need to hire a contractor to do predictive analysis on this?
I mean, I will pay somebody to do the site survey once the building is in place, but I am wondering if typically pay the contractor to execute the predictive analysis instead of just waiting for the real site survey.

A "Predictive Analysis" is not going to guarantee anything. You are better off to wait until the building is build and you have stuff in there befire you hire a company to perform a site survey. Just my thought. An office, might be easier to predict, but not a manufacturing or warehouse facility.

How to add a new universe in population for Predictive Analysis

Post Author: izhar
CA Forum: Performance Management and Dashboards
Hi all members I am working on BOXI R2, SP2 I have to ask that, How to add a new universe in population for "Predictive Analysis". Currently i can only view universe of "Direct Customers and Direct Products"
Any member please help me hereRegards Izhar

Hi Anne,
It really depends on how your portal is set up. And there are 101 ways this could have been done.
I've used the Home Page Framework as an easy to define and extend framework to show applications. I've used it both for ESS and MSS, Using the HPF requires that an application has an iView in the portal.
The main point to be made here is that this is not a Web Dynpro ABAP specific question - but rather one about MSS portal implementation - you would probably be better posting a question in either one of the ESS/MSS or Portal forums.
As it is not a WDA specific question, I'd ask that you kindly close this thread and reopen in another forum.
Thanks for your understanding, it would be nice to be able to answer all questions in all forums (perhaps with some sort of tagging system) but currently forum rules are that questions must be specific to the forum posted.
Thanks,
Chris

Which R packages are required for Predictive Analysis?

Hi,
I have installed SAP Predictive Analysis and have installed R - 3.0.0.

Buisness scenario for Predictive Analysis

Hi All,
I am new to SAP Predictive Analysis. I have gone through all the algorithms present in predictive analysis client tool about when should they be used.
Now I planned to try implementing it on some business scenario.
But the problem I am facing is I am not getting any proper data suitable for PA. I am trying to take BW data into excel which will act as my data source.
Can anyone suggest me what data I should pick up from BW or if possible provide me with some sample data.
Thanks and Regards
Mithilesh Prasad

Hi,
You can also found some datasets on SAP Partner Edge website with the Workbook: SAP Advanced Analytics (SAP PartnerEdge).
If you want to find more dataset, I suggest you to download datasets from UCI Machine Learning Repository to build examples. (UCI Machine Learning Repository). You can start with the dataset Statlog (German Credit Data) with a neural network or a decision tree.

Our Reqirement:
Now we need to Build a Predictive analysis report around this data as follows:
1) The report should show the predictive analysis of liquid consumption by month wise, for each machine level.
Our query:
1) For this requirement what is the predictive analysis algorithm (function) we should use ?
2) What is the implementation procedure on the respective algorithm.
How can we build Types, input Tables ?
How can we build Parameters, how can we determine the Alpha value etc , for our requirement?
Our research and queries on the same.
WE went through a video (HANA Academy - Key Concepts of the Predictive Analysis Library - YouTube)on Single Smooth Algorithm, in that we query on Result.
The input was given as Calendar Id and Sales Amout, where Calendar Id starts from 0 – 23 , what is meant by this Calendar Id ?
And also the result is showing Calendar Id from 2-24 , why it is not considering Calendar 0 and 1
How can we say that the result is predictive and on what basis (like month ,year , date etc).
Thanks and Regards,
Somaraju

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

Please Provide a Key for SAP Predictive Analysis 1.15 32-bit

please provide a needed a key for SAP Predictive Analysis 1.15 32-bit to be used in University Lab computers.

Hi Ye,
I am afraid but the only way today is to delete your document without PA / Lumira.
By default, local files are stored at :
User/Documents/SAP Lumira Documents
In this folder you'll see the list of all the documents you have created with SAP Lumira or SAP PA.
Delete the document that you don't want anymore and (re)start SAP PA.
The delete functionnality from the desktop tool is an idea accepted by the Labs (Delete Files in Lumira Desktop : View Idea), but not implemented yet.
Hope it helps,
Edouard

Can i use SAP Predictive Analysis for this scenario?

Hi guys. I'm new in this subject so I'm a little bit confused about in which cases SAP Predictive Analysis is helpful?
Could it be helpful for this case? I have prices of rice for differente years, from 2007 to 2013. Can SAP Predictive Analysis help me forecast what will be the price of rice for 2014, 2015 and so on?
Which algorithm should I use? Does it come integrated in the tool or is it an add-on?
I´ll appreciate it very much if you could send me the right steps to achieve this.

Hi Erika,
SAP PA has only Triple exponential smoothing algorithm; In most cases, single exponential smoothing would not make any sense [this is available through HANA PAL or R integration with SAP PA];
If you have R integration you should see something like this
In Single exp smoothing only alpha is used;
in double exp smoothing alpha and gamma is used; and all three in gamma.
Why these alpha, beta and gamma... has a big derivation to understand; [let me know if you need any document, I have compiled as on some reference]
What values alpha, beta and Gama should hold in Triple ... or what is the right value, .... actually there are no right value and wrong value for them.
... as for the steps to go in SAP PA, refer below:
Please let me know if you need any assistance ...

Need workflow for Advanced Analysis for Office for Sizing

Hi,
I am in the process of sizing for BO solution .
Part of that exercise is to find out how much cpu and memory are required for AAO?
So i thought trace the AAO workflow and understand which BO services/servers it requires.
If anyone any idea about it workflow, please share.
Thanks,
Srikar

Hi Srikar,
Analysis for office goes directly to SAP BW / SAP HANA for data retrieval, so there is no need to consider it as part of your sizing exercise.
There is a note though about client Hardware and Software requirements:
1466118 - Hardware & Software requirements for Advanced Analysis
The only exception here is the new scheduling capability of Analysis for Office in the BI Platform, in that case the Adaptive Job Server is used.

SAP HANA One and Predictive Analysis Desktop - Time Series Algorithms

I have been working on a Proof-of-Concept project linking the SAP Predictive Analysis Desktop application to the SAP HANA One environment.
I have modeled that data using SAP HANA Studio -- created Analytic views, Hierarchies, etc. -- following the HANA Academy videos. This has worked very well in order to perform the historical analysis and reporting through the Desktop Application.
However, I cannot get the Predictive Analysis algorithms -- specifically the Time Series algorithms -- to work appropriately using the Desktop tool. It always errors out and points to the IndexTrace for more information, but it is difficult to pinpoint the exact cause of the issue. The HANA Academy only has videos on Time Series Algorithms using SQL statements which will not work for my user community since they will have to constantly tweak the data and algorithm configuration.
In my experience so far with Predictive Analysis desktop and the Predictive Algorithms, there is a drastic difference between working with Local .CSV / Excel files and connecting to a HANA instance. The configuration options for using the Time Series Algorithms are different depending upon the data source, which seems to be causing the issue. For instance, when working with a local file, the Triple Exponential Smoothing configuration allows for the specification of which Date field to use for the calculation. Once the data source is switched to HANA, it no longer allows for the Date field to be specified. Using the exact same data set, the Algorithm using the local file works but the HANA one fails.
From my research thus far, everyone seems to be using PA for local files or running the Predictive Algorithms directly in HANA using SQL. I can not find much of anything useful related to combing PA Desktop to HANA.
Does anyone have any experience utilizing the Time Series Algorithms in PA Desktop with a HANA instance? Is there any documentation of how to structure the data in HANA so that it can be properly utilized in PA desktop?
HANA Info:
HANA One Version: Rev 52.1
HANA Version: 1.00.66.382664
Predictive Analysis Desktop Info:
Version: 1.0.11
Build: 708
Thanks in advance --
Brian

Hi,
If you use CSV or XLS data source you will be using Native Algorithm or R
Algorithm in SAP Predictive Analysis.
When you connect HANA, SAP Predictive Analysis uses PAL Algorithm which runs
on HANA server.
Coming to your question regarding difference,
In SAP PA Native Algorithm, we could provide the Data variable, Algorithm
picks the seasonal information from the Data column. Both R and SAP HANA PAL
does not support Date Column. We need configure seasonal information in
Algorithm properties.
R Properties
1) Period : you need to mention the periodicity of the Data
Monthly : (12)
Quarter : (4)
Custom : you can use it for week or Daily or hourly.
2) Start Year: need to mention Start year.
Start year is not used by algorithm for calculating Time series, but it helps
PA to generate Visualization ( Time series chart) by simulating year and
periodicity information.
3) Starting Period:
if your data is Quarterly and you have data recordings from Q2, mention 2 in
start period.
Example.
If the data periodicity is Monthy and my data starts from Feb 1979, we need to provide following information,
Period: 12
Start year: 1979
start Period: 2
PAL Properties. : Same as properties defined in R.
Thanks
