checkcrit: Check critical values

In MultiGroupSequential: Group-Sequential Procedures with Multiple Hypotheses

Check critical values

Description

checkcrit() is a helper function that checks if the critical values are valid.

Usage

checkcrit(
  scrit = qnorm(c(0.01, 0.02, 0.025)),
  salpha = c(0.01, 0.02, 0.025),
  smatrix = diag(3),
  sided = 1
)

Arguments

scrit	Numeric vector of critical values.
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)

Value

List with:

• crit.value: Critical values

• salpha: Cumulative alpha levels passed to salpha argument
