Model structure of random effects BHM

Hi,

I have two somewhat similar questions regarding the model structure of the BHM inside PALAMEDES.

First off, in the Palamedes toolbox for PFHB, as far as I understand, when all parameters are set to 'unconstrained', multiple conditions act like seperate models and do not share any information ...

Re: Weibull function for hierarchical bayesian models

Thanks for the quick reply, this works as intended! I was confused as the page you linked shows a different syntax. I have indeed noticed the differences between the weibull and the gumbel and will stick to the log version of the respective function.

Weibull function for hierarchical bayesian models

Hi all,

I am working with Hierarchical Bayesian models and was wondering if for those models it is also possible to run a Weibull (or Quick) instead of a logistic function as the PF. I have however not been able to find this functionality (yet) in Palamedes for the PFHB.
Does someone know if this ...
