Hi
Jason,
It will be
easier to try to help if given the commands you're using to do the
simulations.

I am running a Monte Carlo experiment using SPSS to generate 1000 samples
of size N from a population that I specify. I have drawn each sample, randomly
split it into 2 groups. For each group I have a time1 and time2 score; thus a
2x2 (group x time) design.
I am then analyzing each sample using ANOVA and ANCOVA methods. I have set
OMS to save out the relevant statistics (F, p, MSE) to two separate SAV files.
The overall experiment will have 54 conditions in which I vary the N and
the correlation between time1 and time2 scores as well as introduce
heterogeneity of group variance.
The problem I am having is that after generating some number of samples and
running analyses, OMS seems to just stop.
This occurs about 50-60% of the time. Other times I get a message that the
SPSS engine has crashed.
I am running version 17.0.1 in Win XP.
any suggestions?
