rmanovab: 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 "mcp1" containing:
• comp
  inference for all pairwise comparisons
• fnames
  names of the factor levels
