aov.test: One-Way Analysis of Variance

Description

aov.test performs one-way analysis of variance (ANOVA).

Usage

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

Value

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

statistic: the analysis of variance test statistic.
parameter: the parameter(s) of the approximate F distribution of the test statistic.
p.value: the p-value of the test.
alpha: the level of significance to assess the statistical difference.
method: the character string "One-Way Analysis of Variance".
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.

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: the level of significance to assess the statistical difference. Default is set to 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.
