Evalutation of alternative cutoff points for defining top feature correlates (gene array dataset).

Cutoff based on Pearson's correlation between GI50 values and gene expression (training set).
Average features per drug do not include “Drug26.”
c-index, weighted average probablistic c-index, assessing predictive accuracy of gene-based scores.

该截断阈值（cutoff）基于训练集中半数生长抑制浓度（GI50）值与基因表达量间的皮尔逊相关系数（Pearson's correlation）确定。
每种药物的平均特征均不包含Drug26。
一致性指数（c-index）及加权平均概率型一致性指数，用于评估基于基因的评分的预测准确性。
