Hello, I am attempting a TSCS imputation, and am having the same problems that others have had in the past with a AMvarnm error message that reads as follows: "_AMvarnm has too many variable names to match each variable in the dataset. Delete variable names, or set _AMvarnm=. for default variable names (default = var1 var2 . . .)." I'm using version 2.0 (7/15/01) for Windows, and the only options I have set are as follows: AMts=1 AMcs=2 AMlagvs=3 AMtstep=1 I've left all else at the default settings. FWIW, I also tried it with various AMempri settings, and got the same error message. Finally, I tried it without declaring it a TSCS dataset just to see if it would run (using the default on all options), and it did. Any suggestions? Thanks, Strom
