Augment existing sampler object to have subject specific epsilon storage

Older sampler object will be missing subject specific scaling parameter (epsilon) storage, and running a stage with an updated pmwg will fail. To fix this you can run the augment_sampler_epsilon function to fill the appropriate array internals with NA values

augment_sampler_epsilon(sampler)

Arguments

sampler

The sampler object to augment

Value

A pmwgs sampler with epsilon array set internally
