WebThis function provides probit analysis for fitting probit and logit sigmoid dose/stimulus response curves and for calculating confidence intervals for dose-response quantiles such as ED50. When biological responses are plotted against their causal stimuli (or logarithms of them) they often form a sigmoid curve. WebThe probit regression procedure fits a probit sigmoid dose-response curve and calculates values (with 95% CI) of the dose variable that correspond to a series of probabilities. For example the ED50 (median effective dose) or (LD50 median lethal dose) are the values corresponding to a probability of 0.50, the Limit-of-Detection (CLSI, 2012) is ...
