不同于机值分析法仍要配出剂量(对数)死亡率(机值)直线式,然后由直线式推定致死中量。这两种结果到底哪一种更反映实际情况是值得讨论的。还有另一种情况,如一次试验中2种剂量水平的死亡率都是50%,用本法分析时2个剂量都是致死中量,这显然是不可能的。因此,遇见这种情况,试验应该重做。虽然机值分析法仍能分析这种结果,但是误差较大,也不一定可靠。
Different from the value analysis method, the dose (logarithm) mortality (machine value) is still to be linear, and then the lethal dose is estimated by the straight line method. It is worth discussing which of these two results actually reflects the actual situation. There is another situation, such as a mortality test at both dose levels are 50%, using the method analysis of the two doses are lethal dose, which is obviously impossible. Therefore, in this case, the test should be redone. Although the value analysis method can still analyze this result, the error is large and not necessarily reliable.
