rmanovab {WRS2}

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
