Hello,
I am trying to implement the TDIST option in the DISTRIBUTION command in my code to deal with non-normal mixture models, such as:

ANALYSIS: TYPE = MIXTURE;
DISTRIBUTION = TDIST;

My data are highly kurtotic.

The problem is that when I run the code, it takes literally ages just to complete few steps. What can I do to deal with this computational problems?

In addition, is it possible to have a look at the single class distributions (in my case, 3) to see if they are normally distributed?

Thanks,
L.

Thanks for the fast reply, the problem is that I do not get any output because it takes too long. It is not feasible to run the model.

What can I alternatively do?

Thanks,
Livia

Check the Tech8 screen printing to look for negative ABS changes and to see how many dimensions of integration you have. Send the input and the data.
