flax: Flaxseed lignan extract intervention microbiome data

In pknight24/KPR: Kernel-penalized regression

Flaxseed lignan extract intervention microbiome data

Description

Baseline microbiome data (X) from a study on the effects of flaxseed lignan extract intervention on enterolactone production (Y). The H matrix is a similarity kernel generated from unweighted Unifrac distances between the samples. The Q matrix is a similarity kernel generated from an Aitchisen variation matrix computed between the p variables. The Y vector is already centered and scaled, and the X matrix has already been normalized with the centered log ratio and then column-centered and scaled.

Usage

data(flax)

Format

A list of the four matrices descibed above.
