Simulate residual variance for merMod objects

Source: R/predictInterval_helpers.R
simulate_residual_variance.Rd

Internal helper that reproduces the sigma-drawing logic from the original `predictInterval()` implementation. It returns a numeric vector of length `n.sims` containing the simulated residual standard deviations.

Usage

simulate_residual_variance(merMod, n.sims)

Arguments

merMod

A merMod object from lme4.

n.sims

Number of simulation draws.

Value

Numeric vector of length `n.sims`.
