6-2 Simple Linear Regression
{"Image DocumentName": "6-2 Simple Linear Regression", "Image ImageDescription": "6-2.5 Checking Model Adequacy. The residuals from a regression model are ei = yi - \u0177i , where yi is an actual observation and \u0177i is the corresponding fitted value from the regression model. Analysis of the residuals is frequently helpful in checking the assumption that the errors are approximately normally distributed with constant variance, and in determining whether additional terms in the model would be useful.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
