FEsim: Simulate fixed effects from merMod FEsim simulates fixed effects from merMod object posterior distributions

Description

Simulate fixed effects from merMod FEsim simulates fixed effects from merMod object posterior distributions

Usage

FEsim(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]

Details

Use the Gelman sim technique to build fixed effect estimates and confidence intervals. Uses the sim function in the arm package

Examples

require(lme4)
m2 <- lmer(Reaction ~ Days + (Days | Subject), sleepstudy)
fe2 <- FEsim(m2, 25)
head(fe2)
