Hi Fritz,

Run the analysis once (without /TEST subcommands), and copy the value for error SS and df, then repeat the analysis with the /TEST subcommand indicating the SS and the df in parenthesis. For example:

UNIANOVA sibs BY sex /METHOD = SSTYPE(3) /INTERCEPT = INCLUDE /CRITERIA = ALPHA(.05) /TEST = sex vs 13892.577 df (1503) /DESIGN = sex .

This code will test the SEX effect against an error term=13892.577/1503=9.243
