It is somewhat of an artifact of the way ANOVA reports results. <BR /> <BR /> Say you have a factor, SEX, with 2 levels as an explanatory variable. Then one of the two levels will have a missing value in the ANOVA table, as two levels just provide for one degree of freedom for the test.<BR /> <BR /> Doc Muhlbaier<BR /> Duke Tue, 03 Feb 2009 14:59:23 GMT Doc_Duke 2009-02-03T14:59:23Z https://communities.sas.com/t5/SAS-Procedures/Missing-value-quot-quot-in-the-ANOVA-output-table/m-p/72073#M20854 After running a stat analysis, I have "."
