表1 2003年9月至2004年8月间采集的棘短身电鳗(Brachyhypopomus draco)雌性个体的性腺指数(gonadosomatic index, GSI)与肝体指数(hepatosomatic index, HSI)的带方差分析(analysis of variance, ANOVA)多元回归分析结果。本次仅展示具有统计学显著性的预测变量。 因变量=性腺指数(GSI);预测变量统计列依次为F值、决定系数(R²)、回归系数、标准误(SE)、t值、p值。 雌性组: 肝体指数(HSI):16.615 0.79 0.624 3.579 0.878 4.076 0.002 水深(cm):25.379 0.847 0.717 0.146 0.029 5.038 0.001 雄性组: 水深(cm):23.307 0.837 0.7 0.008 0.001 6.469 <0.000 溶解氧(O₂, %):24.401 0.919 0.844 0.003 0.001 5.405 0.001 水温(Temp.
