Covariance analysis was used to analyze herbicide efficacy data from rapeseed experiments 摘要采用协方差分析方法,对油菜田除草剂的试验结果进行了分析。
It should be found that in sphere coordinate system the solution covariance is stable and can be used to a simulation / covariance analysis 经过这种变换后,解算参数的协方差是稳定的,可进行仿真协方差分析。
The covariance analysis indicated that the difference was significant between the intercepts in the regression equations , but not between the slopes 协方差分析表明,各回归方程的斜率(体重指数b )之间差异不显著,截距a值差异极显著。
