We use a combination of base robust estimators, specifically M-estimators, and S-estimators, which are termed MM-estimators as described in Yohai (1987).

Our outlier robust estimators can be used as a diagnostic tool yielding different results than OLS when influential outliers are present.

Error estimators can either be classified based on its convergence through the global effectivity index, which is defined as ratio of the estimated error to the true error or can be classified based on the procedures to obtain the estimates.

Therefore, one or more assumptions of the linear regression model will be violated when the model is misspecified, and hence the estimators become biased and inconsistent.

A variety of methods using distance measures have been developed [1]: T-Square sampling [13, 14], Point Centered Quarter Method [15], N-tree sampling [16], random pairs [17], variable area transect [18], closest individual [15], ordered distance [19], compound estimators [20, 21], corrected point-distance [22], nearest neighbor [15], quartered neighbor [23], and angle order [24].

Further, to define the estimators, let T = ([t.sub.1], [t.sub.2], ..., [t.sub.p]) be a p x p orthogonal matrix with T'X'[[OMEGA].sup.-1]XT = [LAMBDA] = diag ([[lambda].sub.1], [[lambda].sub.2], ..., [[lambda].sub.p]), where [LAMBDA] is a p x p diagonal matrix of eigenvalues of X'[[OMEGA].sup.-1]X matrix such that [[lambda].sub.1] [greater than or equal to] [[lambda].sub.2] [greater than or equal to] ...
