Feed: SAS Blogs. Author: Rick Wicklin. I previously showed how to create a decile calibration plot for a logistic regression model in SAS. A decile calibration plot (or "decile plot," for short) is used in some fields to visualize agreement between the data and a regression model. It can be used to diagnose an incorrectly specified model. In principle, the decile plot can be applied to any regression model that has a continuous regressor. In this article, I show how to create two decile plots for an ordinary least squares regression model. The first overlays ... Read More
