stan_checkdivergences: Analyse divergences in a stanfit object

Description

Analyse divergences in a stanfit object

Usage

stan_checkdivergences(sf, nupars = "all")

Arguments

sf

stanfit object.

nupars

either the string 'all', or an integer reflecting how many pars (from first to nupars) to use.

Value

A list of four matrices. $locationsort and $sdsort contian the bivariate interactions of unconstrained parameters, sorted by either the relative location of any divergences, or the relative standard deviation. $locationmeans and $sdmeans collapse across the bivariate interactions to return the means for each parameter.

Examples

# NOT RUN {
library(rstan)
scode <- "
parameters {
  real y[2]; 
} 
model {
  y[1] ~ normal(0, 1);
  y[2] ~ double_exponential(0, y[1]);
} 
"
fit1 <- stan(model_code = scode, iter = 10) 
stan_checkdivergences(fit1)
# }
