REsim: Simulate random effects from merMod REsim simulates random effects from merMod object posterior distributions

Description

Simulate random effects from merMod REsim simulates random effects from merMod object posterior distributions

Usage

REsim(merMod, n.sims = 200, oddsRatio = FALSE, seed = NULL)

Arguments

merMod

a merMod object from the lme4 package

n.sims

number of simulations to use

oddsRatio

logical, should parameters be converted to odds ratios?

seed

numeric, optional argument to set seed for simulations

Value

• a data frame with the following columns [object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Details

Use the Gelman sim technique to build empirical Bayes estimates. Uses the sim function in the arm package

Examples

require(lme4)
m2 <- lmer(Reaction ~ Days + (Days | Subject), sleepstudy)
re2 <- REsim(m2, 25)
head(re2)
