simulate_heterogeneity function

Tidy heterogeneity of variance simulation

This function simulates heterogeneity of level one error variance.

simulate_heterogeneity(data, sim_args, ...)

Arguments

• data: Data simulated from other functions to pass to this function. This function needs to be specified after simulate_fixed and simulate_error.

• sim_args: A named list with special model formula syntax. See details and examples for more information. The named list may contain the following:

  • fixed: This is the fixed portion of the model (i.e. covariates)
  • random: This is the random portion of the model (i.e. random effects)
  • error: This is the error (i.e. residual term).

• ...: Other arguments to pass to error simulation functions.
