In WRS2: A Collection of Robust Statistical Methods

A heteroscedastic one-way repeated measures bootstrap ANOVA for trimmed means.

Description

The rmanovab function computes a bootstrap version of the one-way repeated measures ANOVA for the trimmed means. Homoscedasticity assumption not required. Corresponding post hoc tests can be performed using pairdepb.

Usage

rmanovab(y, groups, blocks, tr = 0.2, nboot = 599, ...)
pairdepb(y, groups, blocks, tr = 0.2, nboot = 599, ...)

Arguments

y	a numeric vector of data values (response).
groups	a vector giving the group of the corresponding elements of y.
blocks	a vector giving the block of the corresponding elements of y.
tr	trim level for the mean.
nboot	number of bootstrap samples.
...	currently ignored.

Value

rmanovab an object of class "rmanovab" containing:

test	value of the test statistic
crit	critical value
call	function call

pairdepb returns an object of class "mcp2" containing:

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