Hi,

I don't know whether it is highly relative to R-INLA group but I am doing some LGM simulations with known true parameters and realize some values/observations and trying to uncover the true parameters.

I want to apply the penalized complexity priors on those parameters. How can I specify the hyperpriors so that the mean of the PC prior distribution equals to the true parameters of the LGM that generates those observations?


Best,
B

the pc-priors is only worked out for some parameters, like precision,
correlations, and so on. do you mean the fixed effects ? for these you
can use Gaussian priors, which should do well

I want to set up the PC prior for besagproper2 CAR random effect. And I have some true precision parameter value and the lambda value. How can I set up the hyperprior parameters so that my true parameters are the hyperprior's mean?


Thanks,
B
