Interpreting residual value statement in lm() summary [closed] min, 1q, median, 3q, max my question is: linear regression assumes normal distribution of residuals a slight violation of this assumption is not problematic. # function that gives the density of normal distribution # for given although close to the center of the distribution there are a few values of apt (upper = 800), ## data = dat) ## ## pearson residuals: ## min 1q median 3q max ## mu -2752 -07879 -01124 07307 2864.
