| 摘要: |
| 对毒力测定的机率值分析法进行研究，结果表明，用机率值γ关于剂量值x的加权直线回归来估计致死中量及其方差不符合统计学原理，建议用x关于y的加权直线回归方法估计。 |

| New opinion of the probit analysis method for toxicity |
|
|
| Abstract: |
| The probit analysis method for toxicity has been studied. The result show that using probit value y about dosage x’s weight regression to estimate half dead dosage (LD50) and it,s variance is not in accordance with the statistical priciple.The x to y’s weight linear regression method should be adopted. |
| Key words: toxicity probit value half dead dosage estimative variance |
