sigma error #48

Closed jesuslovesyiyi closed 3 years ago

jesuslovesyiyi commented 4 years ago

when running the tsclust function on a multivariate model with varying time series length, I run into the error: Parameter 'sigma' must be positive. Do you have any idea what could be the issue? Thanks in advance!

Are you using the GAK distance?

Yes

If you specify sigma for that distance, it must be positive. I don't think the automatic estimate can give a negative result.
