Arguments

fit

a fitted model object (see doFit).

test

specify the test to perform. By default, the first fixed effect in fit will be tested. (see: tests).

sim

an object to simulate from. By default this is the same as fit (see doSim).

fitOpts

seed

specify a random number generator seed, for reproducible results.

...

any additional arguments are passed on to simrOptions. Common options include: [object Object],[object Object],[object Object]#'
