Description:

 

The authors have developed Bayesian regression models that provide predictive capability based on gene expression data derived from DNA microarray analysis of a series of primary breast cancer samples. These patterns have the capacity to discriminate breast tumors on the basis of estrogen receptor status and also on the categorized lymph node status. Their data consisted of estrogen-receptor-positive (ER+) and estrogen-receptor-negative (ER-) tumors.
