Subject: Linear Regression: Dependent variables should not be strings.
X-Git-Tag: fc11-i386-build59^0
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cded1cb84dcf229aa26fa474e52e69109557d83a;p=pspp-builds.git

Linear Regression: Dependent variables should not be strings.

Prevent the gui from selecting string variables as the dependent
variable in a linear regression procedure, since that's not
allowed in such a procedure.
