4   Calculating Sensitivity and Specificity, Difference of Two Proportions, Relative risk and Odds ratio values for two-way contingency tables.
5   Defining the generalized linear models.
6   Building logistic regression model for binary and multiple outcome variables.
7   Building log-linear model for two-way and three-way contingency tables.
8   Building models for matched pairs.
