The worksheet gives data on the reaction time and catalyst used in a chemical production process and an indication of whether or not the final product was of prime quality. Use binary logistic regression to a fit model involving both reaction time and catalyst condition. Catalyst has to be specified as a factor as well as being included in the model. Store the event probabilities (for all observations) and display them plotted against reaction time using Graph>Scatterplot, selecting With Connect and Groups and specifying Catalyst under Categorical variables for grouping. State recommendations that can be made with regard to running the process.
