why does variance of residuals have the same standard deviation why is the variance of the residuals normal? what is the normalized variance of residuals what does normal mean in a regression what is the difference between residuals and normal distributions what is the difference between normal residual and residual what is the difference between a normal and a residual difference between normal errors and normally distributed variance when a regression is normal, the variance is equal to which statement is not the same as an assumption that the residuals are normally distributed? what is the relationship between the error of the regression and the variance of all the data points? if the residuals are normally distributed and the variance is equal, is that the residuals normal? is variance normally distributed what's the relationship between the variance of residuals, the error and the standard deviation? difference between a regression error and a normal residual what is the relationship between regression and residuals what is the difference between an error and a residual difference between normal and residual what is the difference between the variance and the error of the regression? what's the difference between residuals and standard deviations?
