Little's MCAR ERROR: (execution) Invalid argument or operand; contains missing values.

I saw this post Re: the MCAR macro. I was trying it but came across the following error and didn't see any discussion on this particular error. Any ideas where to look?

This problem is from SAS/IML.
Better post it at IML forum:

@Rick_SAS is there.

The error message tells you that the program is trying to compute the quantity

muobsj = mu * Dj;

and one of the quantities on the left hand side (probably mu) contains a missing value.

I am not familiar with the macro, but it looks like mu is the first column of the estimate covariance matrix that PROC MI creates by using the statement

EM outem = emcov;

so check the 'emcov' data set. The covariance matrix should never contain a missing value, so probably the way you are calling the macro is incorrect.
