In iterativeBMAsurv: The Iterative Bayesian Model Averaging (BMA) Algorithm For Survival Analysis

Description

This is an adapted diffuse large B-cell lymphoma (DLBCL) dataset from Rosenwald et al. (2002). This data matrix consists of the expression levels from 36 DLBCL samples (rows), and 100 top univariate genes (columns). This dataset is used as a sample test set in our examples.

Usage

data(trainData)

Format

The data matrix is called testData. Each entry in the matrix represents the expression level of one gene from a DLBCL sample.

Details

We started with the full expression data from Rosenwald et al. (2002), which is available along with corresponding patient information at their supplemental website http://llmpp.nih.gov/DLBCL/. We selected a subset of the 80 test samples, and then performed Cox Proportional Hazards Regression to obtain the 100 genes with the highest log likelihood. The filtered dataset consists of 36 test samples, and it is available at our website http://expression.washington.edu/ibmasurv/protected.
