In merTools: Tools for Analyzing Mixed Effect Regression Models

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

Details

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

Value

a data frame with the following columns

term

Name of fixed term (intercept/coefficient)

mean

Mean of the simulations

median

Median of the simulations

sd

Standard deviation of the simulations, NA if oddsRatio=TRUE

Examples

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