samples_geostan_fit function

Extract samples from a fitted model

Extract samples from a fitted model

Extract samples from the joint posterior distribution of parameters.

## S3 method for class 'geostan_fit' as.matrix(x, ...) ## S3 method for class 'geostan_fit' as.data.frame(x, ...) ## S3 method for class 'geostan_fit' as.array(x, ...)

Arguments

  • x: A fitted model object of class geostan_fit.
  • ...: Further arguments passed to rstan methods for for as.data.frame, as.matrix, or as.array

Returns

A matrix, data frame, or array of MCMC samples is returned.

Examples

data(georgia) A <- shape2mat(georgia, "B") fit <- stan_glm(deaths.male ~ offset(log(pop.at.risk.male)), C = A, data = georgia, family = poisson(), chains = 1, iter = 600) # for speed only s <- as.matrix(fit) dim(s) a <- as.matrix(fit, pars = "intercept") dim(a) # Or extract the stanfit object S <- fit$stanfit print(S, pars = "intercept") samples <- as.matrix(S) dim(samples)
