Fri 05 Feb 2016 03:08:41 PM UTC, comment #6: Downgrading, since Ben pushed a partial fix.	John Darrington <jmd>
Sun 03 Jan 2016 06:28:49 AM UTC, comment #5: I added the warning.	Ben Pfaff <blp>
Sun 03 Jan 2016 06:23:29 AM UTC, comment #4: Elias, I can confirm that filters are ignored. Before we can change that, we need to define the desired behavior for the filtered cases. Should the new variables be system-missing for the filtered cases? Or should the new variables be calculated as they are for other cases, even though their values did not participate in calculating the regression parameters? John, I don't think this is related to bug #44877 (which I know I said I'd fix; I still plan to). For the moment, I'll aim to add a warning if FILTER is present when REGRESSION with a SAVE subcommand is processed.	Ben Pfaff <blp>
Mon 21 Dec 2015 10:22:20 AM UTC, comment #3: It seems you are right. The /SAVE command behaves badly. This is probably related to bug #44877 which is still not fixed.	John Darrington <jmd>
Sun 20 Dec 2015 05:11:34 PM UTC, comment #2: After a lot of experimentation, I found out that Regression command IGNORES ANY FILTER variable when "/SAVE= RESID." subcommand is used for unknown reason!!! Can anyone repeat this bug? I use the following syntax: REGRESSION /VARIABLES= var1 var2 /DEPENDENT= var0 /STATISTICS=COEFF R ANOVA /SAVE= RESID.	elias tsolis <estatistics>
Sun 20 Dec 2015 04:46:40 PM UTC, comment #1: The only way to make it work is the following one: Example: Computing a filter variable based on a cut-off score of a variable (line 1), and then, you apply the filter (line 2), and finally, you compute a new variable based on the old one (the one that is predicted by vars - line three). A Work around to this bug! compute filter2=RES2<60 FILTER BY filter2. compute numall2=numall	elias tsolis <estatistics>
Sun 20 Dec 2015 04:21:13 PM UTC, original submission: Filter variable is not working for regression!!! I have a filter variable 0/1 and when i produce regression statistics together with plots from examine command, i get TWO very different results based on sampel size! Any adjustment of Filter variable has no any impact on sample size used by regression command!!! Check it out!	elias tsolis <estatistics>
