WebbProbit analysis developed from the need to analyze qualitative (dichotomous or poly-tomous) dependent variables within the regression framework. Many response vari-ables are binary by nature (yes/no), while others are measured ordinally rather than continuously (degree of severity). WebbProbit and logistic regression are two statistical methods used to analyze data with binary or categorical outcomes. Both methods have a similar goal of modeling the relationship between a binary response variable and a set of predictor variables, but they differ in their assumptions and interpretation.
