rmanovab: 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, ...)

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

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.
