Webb1 jan. 2015 · For this reason, we cannot use “classic†regression but adjusted regression analysis, called Logit and Probit models (Spuchľaková & Cúg, 2014). Logit analysis is characterized by prediction of probability of the event that either occur or not. Calculated probability is thus equal to either 1 or 0.

The LD or LC values are derived from the curve drawn using working probits and log doses. Antilog of the dose corresponding to respective probit value.
WebbProbit analysis The word probit is an abbreviaton for the ’probability unit’. The principle of this method is the transformation of the sensitivity curve into different coordinates in which the relation becomes linear.
