In the k( ≥2) sample model, the M-estimator of locations is considered as a result of a preliminary test of homogeneity against the two sided alternative . Some asymptotic properties of the preliminary test M-estimator are studied.

For the usual multivariate linear model, preliminary test Mestimation theory is considered in an isotonic setup. Roy's union-intersection principle is incorporated in a formulation of suitable isotonic M-procedures for the preliminary testing compone

Isotonic M-estimation of location parameters in the multivariate simple location model is considered under an orthant restriction on the parameters. The union-intersection principle and theory of M-estimation of location are incorporated in the formu

In a k (≥2) sample model, isotonic estimators of locations θ1, …, θk take into consideration the prior restraint that θ1 ≤ ⋯ ≤ θk. Though these estimators are appealling, they are generally biased. The union-intersection (UI-) principle
