findcrit: Calculate critical values

In MultiGroupSequential: Group-Sequential Procedures with Multiple Hypotheses

Calculate critical values

Description

findcirt() calculates the critical values in the general correlation matrix

Usage

findcrit(
  salpha = c(0.01, 0.02, 0.025),
  smatrix = diag(3),
  sided = 1,
  tol = 1e-10,
  alpha.tol = 1e-11
)

Arguments

salpha	Numeric vector of cumulative alpha levels.
smatrix	General correlation matrix.
sided	Integer vector indicating the side of the test: -1: Reject if test statistic is smaller than or equal to the critical value (one-sided) 1: Reject if test statistic is greater or equal to the critical value (one-sided) 0: Reject if the absolute value of the test statistic is greater than the critical value (two-sided)
tol	Numeric scalar with the tolerance level for computing critical values.
alpha.tol	Numeric scalar. If the alpha increment is less than this, the critical value is set to a large number determined by alpha.tol.

Value

List with element crit.value containing the obtained critical values.
