Re: [Pymc-user] use TkAgg?

[Hanno K. <kl...@ph...>]

Hi Christopher,

thanks for the quick reply. 

Another question is bothering me at the moment (this time maybe a
little less technical):

I understand that the parameters to be estimated are defined via the
sample.parameter method. There I can define a proposed distribution
via dist='some_dist'. However, 'some_dist' needs to be zero-centered,
if I understand the comment in the code correctly. What is the best
way of dealing with a case where you want to have your parameters
greater-equal than zero? Or am I missing the point completely?

Best regards,
Hanno
