mlexp could not find feasible values

[Stefano Pagliarani]

Hello everyone,
I am encountering some issues when running the function mlexp on a country dataset.

My function is:

mlexp (ln(normalden(var1, {xb: var2 var3 var4 var5 _cons}, {sigma})))

On several datasets, the function runs with no issues. Nevertheless, there is one on which it returns an r(491) problem - not being able to find feasible values.

Do you have any ideas on how I can solve the problem?

Thank you all in advance,

Stefano

You could try specifying the initial parameters using the -form()- option.
