parametric_bootstrap.RdGenerate parametric bootstrap replicates of a statistic for a nested linear mixed-effects model.
# S3 method for merMod parametric_bootstrap(model, .f, B, .refit = TRUE) # S3 method for lme parametric_bootstrap(model, .f, B, .refit = TRUE) parametric_bootstrap(model, .f, B, .refit = TRUE)
| model | The model object you wish to bootstrap. |
|---|---|
| .f | A function returning the statistic(s) of interest. |
| B | The number of bootstrap resamples. |
| .refit | a logical value indicating whether the model should be refit to
the bootstrap resample, or if the simulated bootstrap resample should be
returned. Defaults to |
The returned value is an object of class "lmeresamp".
The parametric bootstrap simulates bootstrap samples from the estimated distribution functions. That is, error terms and random effects are simulated from their estimated normal distributions and are combined into bootstrap samples via the fitted model equation.
