Subject: Re: GLM TEST subcommand - specify error term
Content-Type: text/plain; charset="iso-8859-1"
Thank-you for your quick response. If I had only a few dependent
variables, I could do as you recommended and repeat the analysis and
specify the df and MSE in the /TEST subcommand to get the test that I
want. However, the program is going to be used in situations where
there are 20-30 dependent variables and the user would like to automate
the process so that the program would be run once and the output would
be sent to a file for post-processing into a table.
Is anyone familiar with a way that the MS(Error) can be specified as the
error term on a /TEST subcommand within GLM without having to run the
analysis twice and 'manually' entering the df and value for the
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:
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
