Method new()

Create a new ChiSquare object.

Usage

ChiSquare$new(type = c("permu", "asymp"), n_permu = 10000)

Arguments

type

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

n_permu

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

Returns

A ChiSquare object.

Examples

t <- pmt(
    "table.chisq", n_permu = 0
)$test(Table5.4.2)$print()
