Prerequisites for Predictive Analysis ?
Hi Experts,
I desire to be a SAP Predictive Analytics Consultant. I love to play around with data.
So, kindly could anyone tell me how to begin in this path ?
Prerequisites for PA ?
If possible, a small road map for PA ?
Thanks in Advance

Hi Gokulkumar,
Thanks for posting.
I would suggest that you - as you are doing now - look through the articles on this community where you will find good documents that should kick you off in the right direction.
Firstly I would suggest you visit this one:
The magic of Predictive Analytics, HANA & BI.
Secondly here is an end-to-end description of how to use SAP PA & II to solve a predictive task. http://scn.sap.com/docs/DOC-50803
Best regards,
Kurt

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 IzharHi 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,

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 PrasadHi,
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.

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.

Which R packages are required for Predictive Analysis?
Hi,
I have installed SAP Predictive Analysis and have installed R - 3.0.0.
When I try to use the predict functionality in PA, i keep receiving error messages (such as the one attached).
Is it because I havent installed all of the right packages in R? If so, which packages do I need to install in R?
Thanks in a advance for any help.
EmmaHi Emma, you can find this doc about configuration of R for previous version with R 2.15 :
How to Manually Install and Configure Open Source R on Microsoft Windows 7 for SAP PA 1.0
Required packages are:
rJava
RODBC
RJDBC
DBI
monmlp
AMORE
XML
pmml
arules

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,
SomarajuHi JH Yang,
Thanks for the post.
Yes, the BW Connect (offline) feature should be coming to SAP PA.

Predictive Analysis 2.0 - 'BW' connect feature ?
Hello folks,
In the latest Predictive Analysis, do we have 'BW' data connect feature ?
BW offline connection or connection via Lumira is fine.
Looking forward to hearing any response. My customer'd like to know this.
Thanks a lot.

Predictive Algorithm for Churn analysis
Hi,
Can anybody help me with the algorithm which I can use for churn analysis?
Thanks,
AtulHi 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,

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,

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 ...

Nothing displays on Predictive part in SAP Predictive Analysis
Hi,
Earlier, I created a predictive analysis using R-K Means algorithm, and the result was displayed a week ago and saved it. I opened it several times, trying to beautify the same. But today when I opened it, nothing is seen and also I am unable to add analysis as well. I am using SAP Predictive Analysis version 1.16.0.
Please help me how to resolve the issue.Hi Anita, in case this has not be resolved, i just had this issue this morning.
I was unable to add or see any Analysis in Predict Tab.
It seems that if you supress your preference settings
(in C:\Users\yourName\.sapvi\predictive_preferences)
including links to all of your documents, and "repairing" Predictive Analysis by Re-installing it, it works again .
It also seem, after reimporting the original issue document, it is blasted, so you'll have to redo it from scratch.
Hope it will work for you, notice me if it does !

Using Multiple Linear Regression from SAP Predictive Analysis within S&OP
How could I go about using a model exported from SAP Predictive Analysis, say a multiple linear regression model, as a stored procedure in HANA from within S&OP?
Hi Kevin,
You cannot use a model exported from SAP Predictive Analysis in S&OP. S&OP uses the same PAL libraries from HANA for Statistical Forecasting. We enable a few statistical forecasting methods from PAL like exponential smoothing from S&OP.
Thanks,

Is the SAP HANA Predictive Analysis Library used within UDF?
Hello Everyone,
I am an intern at SAP Belfast currently looking at UDF and DDF, and I was wondering if you could answer a few questions for me?
Is the HANA Predictive Analysis Library (PAL) used within UDF? I know that UDF uses regression analysis, and I know that the PAL has functionality for regression analysis, but are they used together? and if so, which algorithm within PAL exactly is used?
I know that the UDF is an Application Function Library. How many of these Application Function Libraries are there within HANA, as I have only come across the AFL which contains the Predictive Analysis Library?
Thanks a lot in advance,
Claire BurnHi Anu,
First double check your own heart. If you really have the passion, then go back to SAP and do what ever you want to do. You will definitely succeed. However if your motivation is primarily influenced by other than (your love for subject), then the question is how far and how long you will be able to stay before those thoughts come back and push you to switch to something else. The key is where your heart is. Only you can help yourself.Good luck.

InfiniteInsight Vs Predictive Analysis
Hi SCN,
What is the main difference between II and PA ??
What is the product history of SAP Predictive Analysis ??
With regards
SateeshHi Sateesh,
For a overview of II you can refer to Henry Bank's excellent blog post:
http://scn.sap.com/community/predictive-analysis/blog/2014/03/11/sap-infinite-insight--introduction-and-overview
Also, to understand how II and PA play together, please refer to our current roadmap:
https://websmp110.sap-ag.de/~sapidb/011000358700001160102012E.pdf
In short, the main difference between PA and II is that II has a limited set of highly automated algorithms and is targeted towards business users while PA has a broad set of algorithms available with a wide range of configuration option to allow custom modeling. PA is targeted more towards experienced Business Analysts and Data Scientists. Both solutions work together with SAP HANA while the integration of PA is - due to historic reasons - still a bit tighter than for II.
I hope this helps!
Best regards,
David
