log-probit analysis

log-probit analysis

a technique for presenting the results of an exposure test on a graph, in which, for example, the dose of a chemical is represented on the x -axis as a log scale and the mortality is represented on the y -axis as a probability scale. The plotted log-probit line is transformed into a more linear shape as a result of the new scales, making it easier to compare results from different tests.

Results of each concentration obtained from each test were subjected to computer log-probit analysis; [EI.sub.50] and [EI.sub.90] values (in ppm or mg/l) were estimated by linear regression analysis.
