Multivariate Least Squares Regression Model with Variable Selection

Curated and Reviewed by Lesson Planet

The risk of contracting an infection in the hospital is low, but it does happen. Learn what risk factors have the highest correlation with hospital-acquired infections in the final lesson of a three-part series. Using the open source R Software, scholars incorporate forward, backward, and stepwise selection strategies within a regression analysis. The software quickly analyzes the multivariate data and provides valuable data analysis information.
