HiddenF {hiddenf}

Hidden F function for matrix data

Description

Fits linear model to ymtx, a matrix of responses of dimension r-by-c. Constructs all possible configurations of rows into two non-empty groups, then, for each configuration, fits full factorial effects models with three factors for group, group-by-column, row and row nested within column. The maximum F-ratio for group-by-column interaction is reported along with Bonferroni-adjusted p-value.

Usage

HiddenF(ymtx)

Arguments

ymtx

A matrix of responses, with rows corresponding to levels of one factor, and columns the levels of a second factor

Value

List-object of class ‘HiddenF’ with components

adjpvalue

(Bonferroni-adjusted) pvalue from configuration with maximal hidden additivity

config.vector

Vector of group indicators for configuration with maximal hidden additivity

tall

A list with components y, row, col

cc

Number of possible configurations
