title: Microcomputer BASIC programs for rapid determination of lethal dosages of biocides using logit transformations.
abstract: The probit analysis model is generally used for the determination of lethal dosages in bioassay applications. However, the logit models, which use the logistic curve instead of the integrated normal curve, could also be effectively used for the determination of lethal dosages and regression coefficients. In this paper, two types of logit models, namely minimum logit chi square and maximum likelihood, have been described in detail for the estimation of the parameters. The results of these two models are also compared with those of the probit model.
