• • • In, robust regression is a form of designed to overcome some limitations of traditional and. Regression analysis seeks to find the relationship between one or more and a. Certain widely used methods of regression, such as, have favourable properties if their underlying assumptions are true, but can give misleading results if those assumptions are not true; thus ordinary least squares is said to be not to violations of its assumptions. Robust regression methods are designed to be not overly affected by violations of assumptions by the underlying data-generating process. In particular, estimates for are highly sensitive to (not robust against). While there is no precise definition of an outlier, outliers are observations which do not follow the pattern of the other observations.

This is not normally a problem if the outlier is simply an extreme observation drawn from the tail of a normal distribution, but if the outlier results from non-normal measurement error or some other violation of standard ordinary least squares assumptions, then it compromises the validity of the regression results if a non-robust regression technique is used.
