Method new()

Create a new JonckheereTerpstra object.

Usage

JonckheereTerpstra$new(
  type = c("permu", "asymp"),
  alternative = c("two_sided", "less", "greater"),
  n_permu = 10000
)

Arguments

type

a character string specifying the way to calculate the p-value.

alternative

a character string specifying the alternative hypothesis.

n_permu

an integer indicating number of permutations for the permutation distribution. If set to 0, all permutations will be used.

Returns

A JonckheereTerpstra object.

Examples

t <- pmt(
    "ksample.jt", alternative = "greater"
