validcovariance

Hello,

The errors that I get on my fitted data do not make sense, so I am trying to understand. If I use strategy=1, I get systematically: HasValidCovariance=false
I do not understand because, a covariance is supposed to be between 2 variables, and I am only fitting one parameter !

By the way, it does not seem that the strategy change the error values.

Thank.
