The number (and percentages) of tissues that give either a false negative or false positive result. For a false negative, a gene has a similar RRD in a cancer tissue to that of the pooled normal distribution (two-sample 1D KS test, P > 0.01). A false positive is scored when a gene has a statistically different RRD than that of the pooled normal in noncancerous breast tissues (P < 0.01).
