purity_data_affy {tidyestimate}

Affymetrix data used to train ESTIMATE algorithm

Description

A data frame containing the ABSOLUTE-measured and ESTIMATE-predicted purity values of 995 tumors. Additionally, stromal and immune scores as calculated by ESTIMATE. All tumors were profiled on Affymetrix arrays, and were used to generate the Affymetrix algorithm.

Usage

purity_data_affy

Format

A data frame with 995 rows and 7 variables:

purity_observed

The purity of a tumor given by ABSOLUTE, ranging from 0 (least pure) to 1 (most pure)

stromal

Stromal infiltration score, as measured by ESTIMATE

immune

Immune infiltration score, as measured by ESTIMATE

estimate

ESTIMATE score, calculated by the sum of immune and stromal scores

purity_predicted

Tumor purity inferred using the ESTIMATE algorithm

ci_95_low

Lower bound of a 95% confidence interval of predicted purity scores

ci_95_high

Upper bound of a 95% confidence interval of predicted purity scores
