Hi all, I have following questions regarding to SAS EM and failed to find the answers online... Thanks for your help.    1). Control point node is to help to simplify the diagram. However, I dont quite understand which result the model node is returning when multiple data sets are linked to it.. For example, if I link 2 data set to 1 model node, result based on which data set will be returned? Or the model node will combine the 2 data sets first and then compute the result?   2). When using Association node for sequence analysis, there are 2 paramters called consolidate time and maximum transaction duration. May I check what's the unit of the 2 fields? For example, if the sequence in my data set is in days and I want to consolidate transactions within 2 days, shall I put "consolidate time = 2 (days) " or "consolidate time = 48 (hours)" ?    3). Does SAS EM support modification of transacion date set? Or data preparation is supposed to be done using SAS or SAS EG? I am asking as I tried to do data filtering using Filter node, and to do data partition using Data Partition node before doing association rule analysis. However, the filtering or data partition didnt work when I put data type = transaction; What's more, I am not supposed to change data type = raw/train since Association node only works for transactional data.    I am not sure whether this is the proper forum for such questions. Any suggestion is appreciated!  ... View more

Seqecmpgroup function in R TraMineR packages is quite helpful to check the rules that are particularly related to some discriminant factors, for example, some rules might be quite different from transactions related to gender. I am wondering whether there is a quicker way to check it using SAS EM? Plan B is to run levels in those factors 1 by 1 and compare the results.. Thanks!  ... View more

I used the same transaction data for both association and market basket node. Result is returned with association node but error appeared under market basket node. May I check what possible causes are?   Error shown in result: Run time error was encoutered. Pls see the log for more details. Error in log: The variable RULE in the DROP, KEEP, or RENAME list has never been referenced. (Appeared in log row 538 right after line, "MPRINT(TRAIN): set EWMS1.MRKBSKT_OUTRULE(keep=RULE transpose);"   I am quite new to SAS EM and your help is appreciated! ... View more
