Dear All,
I would like to generate the variance-covariance matrix after my estimation and then I want to save some specific entries to be used later.
Suppose I have:
When I type matlist s11, I was expected to see the variance of the parameter associated to rep78. Instead, I get a missing value. I cannot understand what is wrong. Any suggestion? Tanks in advance.
