Re: [R] MCMClogit: Cannot calculate marginal likelihood with improper prior

Hi, what I see so far is that you have specified your user.prior.density correctly. The error comes from the prior precision matrix "B0" in combination with the marginal.likelihood set to "Laplace". B0, if not explicitly specified, defaults to zero, which results in eigenvalues of zero. If "La

[R] MCMClogit: Cannot calculate marginal likelihood with improper prior

I'm an undergrad who is new to MCMCpack and I haven't been able to find an answer to my problem online yet: I'm attempting to run MCMClogit with a Cauchy proper prior but I'm getting the warning "Cannot calculate marginal likelihood with improper prior" (my purposes require the marginal likelihood
