In lorad: Lowest Radial Distance Method of Marginal Likelihood Estimation

Log (or log-ratio) transform parameters having constrained support

Description

Log-transforms parameters with support (0,infinity), log-ratio transforms K-dimensional parameters with support a (K-1)-simplex, logit transforms parameters with support [0,1], and leaves unchanged parameters with unconstrained support (-infinity, infinity).

Usage

lorad_transform(params, colspec)

Arguments

params	Data frame containing a column for each model parameter sampled as well as one or more columns that, when summed, constitute the log joint posterior kernel
colspec	Named character vector matching each column name in params with a column specification

Value

A new data frame comprising transformed parameter values with a final column holding the log joint posterior kernel
