Is Cook

WebI don't know specifically about Cook's distance, but the classical example that shows this distinction is regression in L 2 versus L 1 loss functions. L 2 is smooth, least-mean-squared (associated with Gauss) and weighs outliers quadratically. L 1 loss is robust, polyhedral least-absolute-sum (associated with Laplace) and weighs outliers linearly. WebCook's distance by centered leverage value The resulting scatterplot shows a few unusual points. 3000GT has a large Cook's distance, but it does not have a high leverage value, so while it adds a lot of variability to the regression estimates, it likely did not affect the slope of the regression equation. The In statistics, Cook's distance or Cook's D is a commonly used estimate of the influence of a data point when performing a least-squares regression analysis. In a practical ordinary least squares analysis, Cook's distance can be used in several ways: to indicate influential data points that are particularly worth … Ver mais Data points with large residuals (outliers) and/or high leverage may distort the outcome and accuracy of a regression.
