rmanovab {WRS2} | R Documentation

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

### Description

The `rmanova` 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.

### 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
