Extract Posterior Draws or Bootstrap Resamples from marginaleffects Objects

Usage

get_draws(x, shape = "long")

Arguments

x

An object produced by a marginaleffects package function, such as predictions(), avg_slopes(), hypotheses(), etc.

shape

string indicating the shape of the output format:

  • "long" (default): long format data frame

  • "PxD" (fastest): Matrix with parameters as rows and draws as columns

  • "DxP": Matrix with draws as rows and parameters as columns

  • "rvar": Random variable datatype (see posterior package documentation).

Value

A data.frame with drawid and draw columns.

Details

If DxP and PxD and the names returned by coef(x) are unique, marginaleffects sets parameter names to those names. Otherwise, it sets them to b1, b2, etc.
