This paper studied the least trimmed absolute deviations (LTAD) estimator of location. The LTAD estimator is defined by minimizing the least sum of absolute deviations on all possible half-samples. Consistency and asymptotic normality of the LTAD are derived. A comparison of asymptotic variances of the LTAD, Rousseeuw's least median of squares (LMS) and LTS are carried out.
