Calculate sample size

Usage

get_n(
  power,
  es0,
  es1,
  R,
  alpha = 0.05,
  k,
  method = c("ols", "gls"),
  df_method = c("vd", "vob", "vlt"),
  n0_range = c(2, 1000),
  tolerance = 1e-06
)

Arguments

power: target power
es0: effect size in endpoint 1
es1: effect size in endpoint 2
R: correlation matrix between endpoints
alpha: significance level
k: sample size ratio of treatment vs placebo
method: obrien "ols", "gls"
df_method: degrees-of-freedom method (one of: vd, vob, vlt)
n0_range: range of size in placebo to be searched
tolerance: the desired accuracy (convergence tolerance)
