Wilksn: Wilk's Lambda for n-group multiple comparisons

In MAVTgsa: Three methods to identify differentially expressed gene sets, ordinary least square test, Multivariate Analysis Of Variance test with n contrasts and Random forest.

Description

To compute Wilk's Lambda statistic for multivariate analysis of variance and multiple comparisons.

Usage

Wilksn(Y, class, type = c("Tukey", "Dunnett", "Sequence"), base = 1)

Arguments

Y	Data matrix; row is sample; each column is variable(gene).
class	Vector defining the clinical outcome of the samples.
type	Type of contrast
base	An integer to denote which group is considered the baseline group for Dunnett contrasts.

Value

Wilk's Lambdas for MANOVA and multiple comparisons are returned.

Note

R > 2.13.2
