Method new()

Create a new Sign object.

Usage

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

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.

correct

a logical indicating whether to apply continuity correction in the normal approximation for the p-value.

Returns

A Sign object.

Examples

t <- pmt(
    "paired.sign",
    alternative = "greater", n_permu = 0
)$test(
    rep(c(+1, -1), c(12, 5)), rep(0, 17)
)$print()
