In WRS2: A Collection of Robust Statistical Methods

Bootstrap version of the heteroscedastic one-way ANOVA for trimmed means.

Description

Test the hypothesis of equal trimmed means using a percentile t bootstrap method. Corresponding post hoc tests are provided in mcppb20.

Usage

t1waybt(formula, data, tr = 0.2, nboot = 599, ...)
mcppb20(formula, data, tr = 0.2, nboot = 599, ...)

Arguments

formula	an object of class formula.
data	an optional data frame for the input data.
tr	trim level for the mean.
nboot	number of bootstrap samples.
...	currently ignored.

Value

Returns an object of class t1waybt containing:

test	value of the test statistic
p.value	p-value
Var.Explained	explained amount of variance
Effect.Size	effect size
nboot.eff	effective number of bootstrap samples
call	function call

mcppb20 returns an object of class "mcp1" containing:

comp	inference for all pairwise comparisons
fnames	names of the factor levels
