    Choosing prior for the regression coefficients in the logistic regression

    I'm trying to model Bayesian logistic regression model (using JAGS in R) with my dependent variable (status: 0=alive, 1 death) & independent variable (age) in the categorical form (0=patients < 65 yrs old, 1=patients >=65 yrs old). I'm using normal dist. as a prior for constant term, b0 and...

    Poisson/Gamma model (empirical Bayes), prior distribution parameters calculation

    Hello everyone, I want to calculate the α and β estimates of the prior (Gamma) distribution for the Poisson/Gamma model based on the Empirical Bayes method, however I cannot find any closed-form equations from literature. Any idea? Thank you in advance for your help!
