Thanks for the update: SAS will give a very similar result. According to Helmut SAS assigns 0 to negative variance values and we see this in the post from India. We have to keep in mind that this data set is simulated and this is surely the source of the problem?

Once you complete SAS work then we can compare results of the upper confi­dence interval calculation for sigmaD2 comparison given in the Guidance. I have already an Excel spreadsheet plus chi squared from another program to provide the upper CI. I need to verify my results by comparison with someone else.

So far what I see is very high values for upper CI, but this could be due to lack of an actual data set
