Part A provides the nonstatistician a basic understanding of the mathematical models associated with multivariate analyses, i.e., multiple linear regression, multiple logistic regression, Cox proportional hazards regression, and discriminant function analysis. Part B focuses on a basic understanding of conjunctive consolidation with a practical demonstration of how it can be performed. …
