WARNING: Singular covariance - coefficients are not unique

Postby sohansust » Wed Oct 30, 2013 3:55 am

Dear all,
I am trying to estimate the markov switching model.
But when I run the model I got the error
'WARNING: Singular covariance - coefficients are not unique'
and there is no std error and s-statistic values.
Can somebody help plzzzzzzzz.
thanks

you may try to set a initial value for your estimation, I've tried and I worked!
