Average Marginal Effects

Description

Provides the average marginal effects of a GLM model with bootstrapped confidence intervals. Similar results would be obtained from using margins::margins().

Usage

frames(model, ci_type = "perc", boot = 100, ci = 0.95)

Arguments

model

the model object

ci_type

the type of boostrapped confidence interval; options are "perc", "basic", "bca"

boot

the number of bootstrapped samples; default is 100

ci

the confidence interval; the default is .975 which is the 95% confidence interval.

Details

Using the average marginal effects as discussed by Tamas Bartus (2005), the coefficients are transformed into probabilities (for binary outcomes) or remain in their original units (continuous outcomes).
