Sub-type specific gene signature decreases the prediction error rate. Estimation of prediction error rate by random sampling of training-testing samples was restricted to Estrogen-Receptor positive (ER+) samples, and its error rate (ER+ only) was compared with that of total (both ER+ and ER-) samples.
