SAS Essential Training: 2 Regression Analysis for Healthcare Research

via LinkedIn Learning

Overview

Deepen your SAS knowledge by learning how to conduct a regression analysis of a health survey data center using this popular data analytics platform.

SAS is a venerable data analytics platform that boasts millions of users worldwide and a slew of useful features. In this course, instructor Monika Wahi helps you deepen your SAS knowledge by showing how to use the platform to conduct a regression analysis of a health survey data center. Throughout the course, Monika demonstrates how to conduct regression analyses and present your model results in tables. She shows how to develop and present a linear regression model using PROC GLM as part of a hypothesis-driven analysis; how to do a logistic regression model in both PROC GENMOD and PROC LOGISTIC; and how to present and interpret your linear and logistic regression models. To wrap up, she goes over issues in regression and provides a few helpful tips.
