type="main" xml:id="sjos12020-abs-0001" <title type="main">ABSTRACT</title>In this paper, we study the problem of testing the hypothesis on whether the density f of a random variable on a sphere belongs to a given parametric class of densities. We propose two test statistics based on the L-super-2 and L distances between...

Let "X" be a "d"-variate random vector that is completely observed, and let "Y" be a random variable that is subject to right censoring and left truncation. For arbitrary functions "&phiv;" we consider expectations of the form "E"["&phiv;"("X", "Y")], which appear in many statistical problems, and we...

A new class of estimators is introduced for estimating the parameter ([theta]10, [theta]20) in the linear regression model y = E[YX = x] = [theta]10 + [theta]20x. Given independent copies {(X1, Y1),..., (Xn, Yn)} of the two-dimensional random vector (X, Y), these estimators are derived from...
