In jeff324/powder: Power posterior sampling via differential evolution

Description

Reshapes the subject-level parameters in Powder.Individual or Powder.Hierarchical objects to a dataframe for easier analysis.

Usage

reshape.theta(pow.out, pars = NULL, with.burnin = FALSE, ...)

pars	subset of parameters to reshape. Defaults to all parameters.
with.burnin	if false, burnin is discarded
...	additional arguments
subject	subset of subjects to reshape. Defaults to all subjects.

Value

A dataframe with columns corresponding to parameter, iteration, chain, value, and subject if Powder.Hierarchical object.

Examples

## Not run: 
data('null')
lba = LBA$new()
#low number of samples for illustration purposes
out = powder(model=lba,data=null,burnin=10,n.samples=10,method='posterior')
phi_df = reshape.phi(out)

## End(Not run)
