Join this webinar to learn the mechanics behind simple linear regression and how to perform it using both SAS®9 and SAS® Viya®. Linear regression is used across a wide range of fields to help predict a continuous target variable, such as “weight.” Simple linear regression uses only...

Within the range of .20 to .80 for the predicted probabilities, the linear probability model is an extremely close approximation to the logistic model. Even outside that range, OLS regression may do well if the range is narrow. It’s not uncommon for logistic regression to break down complet...

In SAS, stepwise linear regression is implemented through PROC REG. In open-source R, it is implemented through the function step. The problem with using the function step in R is that the size of the data set that can be analyzed is severely limited by the requirement that all co...
