No. I replaced outliers by the next highest value. So these are 'estimations'. I have to perform a mixed design anova (1 between and 1 within subject factor). Because of the estimations, I need to correct the degrees of freedom for the error term (i.e. df2 in this formulation: F(df1, df2)). However, if you correct degrees of freedom, your F-value, p-value and eta squared partial change. Calculating these values by hand is complex.

So I was wondering whether there is an easy way to correct these degrees of freedom for the error term in SPSS so that these values are calculated automatically?
