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.Ī statistical error (or disturbance) is the amount by which an observation differs from its expected value, the latter being based on the whole population from which the statistical unit was chosen randomly. 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). 4 Other uses of the word "error" in statistics.Heteroscedasticity and Autocorrelation Consistent Regression Standard Errors.Heteroscedasticity Consistent Regression Standard Errors.( September 2016) ( Learn how and when to remove this template message) Please help to improve this article by introducing more precise citations.
