Other fascinating properties for estimators contain: UMVUE estimators which have the lowest variance for all possible values with the parameter to be believed (this is usually A neater residence to confirm than efficiency) and consistent estimators which converges in chance for the genuine price of this sort of parameter.
Several statistical approaches seek out to minimize the residual sum of squares, and these are definitely identified as "ways of the very least squares" in contrast to The very least absolute deviations. The latter offers equivalent excess weight to little and big errors, although the previous offers a lot more weight to substantial mistakes. Residual sum of squares is also differentiable, which supplies a helpful assets for undertaking regression. Minimum squares applied to linear regression known as ordinary least squares approach and minimum squares applied to nonlinear regression is called non-linear least squares.
