Combine MCMC samples of two objects

Combines samples of two MCMC objects (with the same parameters, chains and iterations) using a function.

combine_samples(x, x2, fun = mean, ...)

Arguments

x

An MCMC object.

x2

a second MCMC object.

fun

The function to use to combine the samples. The function must return a scalar.

...

Unused.

Value

The combined samples as an MCMC object with the same parameters, chains and iterations as the original objects.
