WebCook’s distance (Di ) Summary measure of the influence of a single case (observation) based on the total changes in all other residuals when the case is deleted from the estimation process. WebCook’s Distance is a measure of an observation or instances’ influence on a linear regression. Instances with a large influence may be outliers, and datasets with a large number of highly influential points might not be suitable for linear regression without further processing such as outlier removal or imputation.

This is because the definition of Cook's distance is the distance the LFC for the group would move if the sample were removed. So I wouldn't worry about the Cook's distances here. Everything looks ok.

WebOther than that, I guess it's just that data is noisy, with high variability, hence the large Cook's distances. Still, some of the genes that I get out of the differential expression analysis do display nice trends. Some others are clearly flagged as significant just because there is one sample that is a count outlier. 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.
