On Predictors and Estimators under a Constrained Partitioned Linear Model and its Reduced Models

چکیده
In this study, we consider a partitioned linear model with partial parameter constrains, known as constrained (CPLM), and its reduced models. A group of formulas on best unbiased predictors (BLUPs) estimators (BLUEs) in CPLM is derived via some quadratic matrix optimization methods, further many basic properties the are established under general assumptions. Our main purpose to derive various inequalities equalities for comparison covariance matrices BLUPs BLUEs

15 صفحه اولRidge Stochastic Restricted Estimators in Semiparametric Linear Measurement Error Models
In this article we consider the stochastic restricted ridge estimation in semipara-metric linear models when the covariates are measured with additive errors. The development of penalized corrected likelihood method in such model is the basis for derivation of ridge estimates. The asymptotic normality of the resulting estimates are established. Also, necessary and sufficient condition...
