Non Independence of Error Variables
{"Image DocumentName": "Non Independence of Error Variables", "Image ImageDescription": "A time series is constituted if data were collected over time. Examining the residuals over time, no pattern should be observed if the errors are independent. When a pattern is detected, the errors are said to be autocorrelated. Autocorrelation can be detected by graphing the residuals against time.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
