On Local Moments

Müller, Hans-Georg; Yan, Xin - In: Journal of Multivariate Analysis 76 (2001) 1, pp. 90-109

We introduce the concept of local moments for a distribution in p, p[greater-or-equal, slanted]1, at a point z[set membership, variant]p. Local moments are defined as normalized limits of the ordinary moments of a truncated version of the distribution, ignoring the probability mass falling...

Asymptotics of Estimating Equations under Natural Conditions

Yuan, Ke-Hai; Jennrich, Robert I. - In: Journal of Multivariate Analysis 65 (1998) 2, pp. 245-260

In a variety of statistical problems one needs to solve an equation in order to get an estimator. We consider the large sample properties of such estimators generated from samples that are not necessarily identically distributed. Very general assumptions that lead to the existence, strong...

Testing of a Structures Covariance Matrix for Three-Level Repeated Measures Data.

Roy, Anuradha; Leiva, Ricardo - College of Business, University of Texas-San Antonio

-level (multiple time points (p), multiple sites (u), and multiple response variables (q)) multivariate data. Testing of such …-covariance matrix. This hypothesis procedure not only can test the hypothesis on three-level multivariate data, but also can test the … hypotheses on two-level multivariate data as special cases. We provide the maximum likelihood estimates of the unknown population …
