Statistical Procedures 14 Body weight length: T test HOMIM microarray signals =0, if lack of signal =1, f signal≥1. Prevalence distribution between groups: x test, a=0.005 PLS-DA 样本点个数少于变量个数 ·自变量存在严重多重相关性的条件下进行回归建模 ·易于辨识系统信息与噪声• Body weight & length: T test. • HOMIM microarray signals: • =0, if lack of signal; • =1, if signal ≥ 1. • Prevalence distribution between groups: χ 2 test, α=0.005. •PLS-DA • 样本点个数少于变量个数 • 自变量存在严重多重相关性的条件下进行回归建模 • 易于辨识系统信息与噪声 Statistical Procedures 14
