Subject:      Mixed Model ANOVA
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

I have spent much of today trying to get a linear mixed-model repeated
measures ANOVA to run in SPSS 18. I know my data is structured properly
with a single row for each data point and the correct total number of
rows for my two within variables, 3 levels of one variable and 4 levels
of the other. But I get a processor crash and program terminating
message whenever I try to run it. Here is what the syntax looks
like that is in the output file after the crash. I don't know what the
_ASSERT line refers to. Any help with this vexing problerm would be
appreicated. I don't have a lot of hair to pull out anymore....
