Warning message in SPSS


New Member
Hi, just wondering if anyone can shed any light on this error message that I get in SPSS:

"For models with dependent variable [name], the following variables are constants or have missing correlations: [names]. They will be deleted from the analysis."

I'm currently thinking it might be because all but one or two respondents answered "no" (coded as zero) for those variables, but the same applies to some of the other independent variables and yet they were not deleted.

Thanks in advance for any suggestions!
