This vignette describes the mp_power() workflow and how
to summarize results with summary().
d <- mp_design(clusters = list(subject = 20), trials_per_cell = 4)
a <- mp_assumptions(
fixed_effects = list(`(Intercept)` = 0, condition = 0.4),
residual_sd = 1,
icc = list(subject = 0.1)
)
scn <- mp_scenario_lme4(
y ~ condition + (1 | subject),
design = d,
assumptions = a,
test_method = "wald"
)
res <- mp_power(scn, nsim = 10, seed = 42)
