基于农药毒力计算的6个统计分析软件比较

Comparison of Six Statistical Analysis Software Based on Pesticide Toxicity Calculation

选用了能够用于农药毒力数据机率值分析的通用软件(SAS、SPSS和DPS)和专门程序(Polo、BA和EPA机率值分析程序),以二化螟对三唑磷的室内毒力数据为例,比较分析不同统计分析软件的计算结果。结果表明,当对照组死亡率为0时,6个软件程序计算得到的LD值(LD5、LD50和LD95)、截距和斜率等基本相等,但是LD值的95%置信限有差异。当对照组死亡率不为0时,发现6个程序计算得到的毒力资料数值都有差异,其中LD(LD5、LD50和LD95)、截距和斜率的数值相差较小,但是LD值的95%置信限差异较大。

Six statistical analysis software （SAS, SPSS, DPS, Polo, BA and EPA ） were used to calculate the pesticide toxicology data. When the mortality in control group was 0, the Lethal dose （LD5 , LD50 and LD95 ）, intercept and slope were almost equal, but the 95 % confi- dence limits calculated by the six statistical analysis software were different. When the mortality in control group was not 0, the pesticide toxi- cology data calculated by six statistical analysis software （SAS, SPSS, DPS, Polo, BA and EPA） were all different. There were slight differ- ences between the Lethal dose （ LD5 , LD50 and LD95 ）, intercept and slope, but there were large differences between the 95% confidence lim- its calculated by the six statistical analysis software.
