"Suppose there is a series of observations from a univariate distribution and we want to estimate the mean of that distribution (the so-called location model). In this case, the errors are the deviations of the observations from the population mean, while the residuals are the deviations of the observations from the sample mean. A statistical error (or disturbance) is the amount by which an observation differs from its expecte… " - Fitting deviation
