In stan-dev/cmdstanr: R Interface to 'CmdStan'

Transform a set of unconstrained parameter values to the constrained scale

Description

The ⁠$constrain_variables()⁠ method transforms input parameters to the constrained scale.

Usage

constrain_variables(
  unconstrained_variables,
  transformed_parameters = TRUE,
  generated_quantities = TRUE
)

Arguments

unconstrained_variables	(numeric) A vector of unconstrained parameters to constrain.
transformed_parameters	(logical) Whether to return transformed parameters implied by newly-constrained parameters (defaults to TRUE).
generated_quantities	(logical) Whether to return generated quantities implied by newly-constrained parameters (defaults to TRUE).
