Description

Compute the summary statistics for the effective sample size (ESS) across posterior samples for possibly many variables

Usage

1
getEffSize(postX)

Arguments

postX

An array of arbitrary dimension (nsims x ... x ...), where nsims is the number of posterior samples

Value

Table of summary statistics using the function summary().

# ESS for iid simulations:
rand_iid = rnorm(n = 10^4)
getEffSize(rand_iid)

# ESS for several AR(1) simulations with coefficients 0.1, 0.2,...,0.9:
rand_ar1 = sapply(seq(0.1, 0.9, by = 0.1), function(x) arima.sim(n = 10^4, list(ar = x)))
getEffSize(rand_ar1)
