Extracting derived parameters

[jabienias]

I'm sorry if this seems a simple question, but I cannot see how to obtain the derived parameter values after running the model (a, i, t14 and t23), other than estimating them from the corner diagram.

Any help gratefully received.

Hi John,

Sorry, I should have documented this better. At the moment, you first get an xarray DataSet containing the posterior samples as

df = ta.posterior_samples()

after which you can access the model parameter posterior samples as

df.posterior.b_1

and the derived parameter posterior samples as

df.derived_parameters.t14_1

Hope this helps!

Cheers,
Hannu

That's fixed it! Many thanks.
