F. 這一計算結(jié)果對上述三項(xiàng)生長發(fā)育指標(biāo)進(jìn)行了單因素的方差分析，可見： X1: SS = , F = X2: SS = , F = X3: SS = , F = 差別均有顯著性，說明三項(xiàng)生長發(fā)育指標(biāo)各地區(qū)間的差別均有顯著性。通常有四種方法： Pillai軌跡：V = Wilks λ值：W = Hotelling軌跡：T = Roy最大根：R = 式中λmax為最大特征值, λi為第i個特征值,s為非零特征值個數(shù)。如X。 Multivariate test for Homogeneity of Dispersion matrices Pooled withincells VarianceCovariance matrix X1 X2 X3 X1 X2 X3 Correlation matrix with Standard Deviations on Diagonal X1 X2 X3 X1 X2 .680 X3 .595 .886 Cell Number .. 3 Sum of Squares and CrossProducts matrix X1 X2 X3 X1 X2 X3 Correlation matrix with Standard Deviations on Diagonal X1 X2 X3 X1 X2 .697 X3 .482 .734 Cell Number .. 2 Sum of Squares and CrossProducts matrix X1 X2 X3 X1 X2 X3 Cell Number .. 1 (Cont.)
