FEsim {merTools} | R Documentation

## 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)
