bwss.matrix: Between and within sums of squares for matrix
In limma: Linear Models for Microarray Data

Description Usage Arguments Details Value Author(s) See Also

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.

1	bwss.matrix(x)

`x`	a numeric matrix.

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.

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`.
