rmanovab function

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

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.

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.

Returns

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
