gene {xtune}

Simulated gene data to predict weight loss

Description

The simulated gene data contains 50 observations, 200 predictors, and an continuous outcome, bone mineral density. The external information Z is four previous study results that identifies the biological importance of genes.

Usage

data(gene)

Format

The gene object is a list containing three elements:

• GeneExpression: Matrix of gene expression predictors.

• bonedensity: Continuous outcome variable

• PreviousStudy: Whether each gene is identified by previous study results.
