Description Usage Arguments Details Value Author(s) See Also

Description

Sums of squares between and within the columns of a matrix. Allows for missing values. This function is called by the anova method for MAList objects.

Usage

1

Arguments

x

a numeric matrix.

Details

This is equivalent to a one-way analysis of variance where the columns of the matrix are the groups. If x is a matrix then bwss.matrix(x) is the same as bwss(x,col(x)) except for speed of execution.

Value

A list with components

bss

sums of squares between the column means.

wss

sums of squares within the column means.

bdf

degrees of freedom corresponding to bss.

wdf

degrees of freedom corresponding to wss.
