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
