Cook's distance formula
WebThe Cook's distance measure for the red data point (0.701965) stands out a bit compared to the other Cook's distance measures. Still, the Cook's distance measure for the red data point is gretaer than 0.5 but less than 1. Therefore, based on the Cook's distance measure, we would perhaps investigate further but not necessarily classify the red ...

The distance formula is the formula, which is used to find the distance between any two points, only if the coordinates are known to us. These coordinates could lie on x-axis or y-axis or both. Suppose, there are two points, say P and Q in an XY plane. The coordinates of point P are (x 1,y 1) and of Q are (x 2,y 2).

WebCook’s Distance in Panel Settings Despite estimation by OLS, Cook’s formula in (3) cannot be applied, as the updating equation in (1) does not provide the correct estimates when a row is deleted from the data Instead this provides the OLS estimates when a row is removed from the transformed variables based on the full sample.
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 … See more Data points with large residuals (outliers) and/or high leverage may distort the outcome and accuracy of a regression. Cook's distance measures the effect of deleting a given observation. Points with a large Cook's … See more $${\displaystyle D_{i}}$$ can be expressed using the leverage ($${\displaystyle 0\leq h_{ii}\leq 1}$$) and the square of the internally Studentized residual ( See more • Outlier • Leverage (statistics) • Partial leverage See more There are different opinions regarding what cut-off values to use for spotting highly influential points. Since Cook's distance is in the metric of an F distribution with $${\displaystyle p}$$ and $${\displaystyle n-p}$$ (as defined for the design matrix See more High-dimensional Influence Measure (HIM) is an alternative to Cook's distance for when $${\displaystyle p>n}$$ (i.e., when there are more predictors than observations).
