Hi. I have run Latent Class Analysis on my data using the Extensions utility. While it creates three groups, there's no variable indicating which respondent belongs in which group. (When I try to assign a variable to hold the scores, the variable stays blank.) Can someone assist? Thx!

The predicted class and related information are saved to a new dataset that you specify. You need to include an ID variable if using this feature so that you can merge these variables into your main dataset.

Here is an example syntax using the employee data.sav file shipped with Statistics.

STATS LATENT CLASS MANIFESTVARS=educ jobcat COVARIATES=jobtime prevexp CLASSES=3

/OPTIONS MISSING=INCLUDE REPETITIONS=10 MAXITER=1000 TOL=.0000000001

/OUTPUT GRAPHS=YES

/SAVE SCOREDS=predicted IDVAR=id

Thank you, Jon. When I try running it, I get this error message:

Dataset name for keyword PREDCELLDS of subcommand SAVE is missing or invalid.

So what am I doing wrong?

Please paste and post your syntax.

Here we go:

STATS LATENT CLASS MANIFESTVARS=Q9A_01 Q9A_02 Q9A_03 Q9A_04 Q9A_05 Q9A_06 Q9A_07 Q9A_08 Q9A_09

/SAVE PREDCELLDS=2580 Harris Data 4A SCOREDS=2580 Harris Data 4B IDVAR=responseID FILLER=IGNORE.

Dataset names follow the same rules as variable names, so they have to start with a letter and cannot contain blanks.

That did it. Thank you, sir!
