When I run Proc Calis, the log window shows me the warning message as " 12 observations omitted due to missing ID values." I don't know how to resolve this problem. Can any one help me answer this question? Is there any other statement needed to add in the statement of PROC CALIS? Thank you.
I'm no CALIS expert, but I think you either have to accept that 12 rows wouldn't be part of the analysis, or try to clean up you source data. This quote from on-line doc might give some clues as well:
If the DATA= data set contains raw data (rather than a covariance or correlation matrix), observations with missing values for any variables in the analysis are omitted from the computations. If a covariance or correlation matrix is read, missing values are allowed as long as every pair of variables has at least one nonmissing value.
