Add a conditional prior for bayesian model

[Clg]

Dear all,

I would like to run a Bayesian linear mixed model by adding historical data to amend the prior distribution of the placebo arm. Therefore, I would like to specify a conditional prior distribution for the placebo effect with a normal distribution. 

Is it possible to do this with PROC BGLIMM or should I use PROC MCMC? 

In my model I don't have a variable Placebo but I have a variable for Treatment (with Placebo and Active treatment as modalities). 

Thank you in advance,

Regards,

Clemence

Good question.
With PROC MCMC it's definitely possible.

With PROC BGLIMM ... I don't know 🤔.

I have moved your question to the "Statistical Procedures" - board.
