James Second Order Test

Description

james.test performs James second order test.

Usage

james.test(formula, data, alpha = 0.05, na.rm = TRUE, verbose = TRUE)

Arguments

formula	a formula of the form lhs ~ rhs where lhs gives the sample values and rhs the corresponding groups.
data	a tibble or data frame containing the variables in formula.
alpha	a significance level. Defaults alpha = 0.05.
na.rm	a logical value indicating whether NA values should be stripped before the computation proceeds.
verbose	a logical for printing output to R console.

Value

A list with class "jt" containing the following components:

statistic	the James second order test statistic.
criticalValue	the critical value of the James second order test statistic.
alpha	the level of significance to assess the statistical difference.
method	the character string "James Second Order Test".
data	a data frame containing the variables in which NA values (if exist) are removed.
formula	a formula of the form lhs ~ rhs where lhs gives the sample values and rhs the corresponding groups.
