This paper focuses on finding solutions of generalized Sylvester-type matrix equations over the quaternion skew-field. We express the general least–squares solutions, and perhermitian, skew-perhermitian least-squares solutions of AXB+CYD=E and AXB+CXD=E over the quaternion skew-field in terms of...

of the chelate cycle. N,N-Diethyl-1-(2-vinylphenyl)propan-1-amine is a limiting case; its interaction withInd IImakes it possible to isolate the corresponding ruthenium chelate in a low yield (5%). Catalytic activity of the synthesized complexes was tested in RCM reactions and compared with...

This paper deals with parameter estimation for a minimum-type distribution function - Two modifications of the least-squares method (LSM) proposed by Bain and Antle are investigated and compared by means of the Monte Carlo study. The first one is an estimation of θ1, θ2, a by solving...
aKelejian and Prucha (1998) describe the theoretical background for a generalized spatial two-stage least-squares procedure for estimating a model of the type described in this section. kelejian和Prucha (1998年)描述理论背景为广义空间两阶段最小平方的方法为估计在这个部分描述的类型的模型。[translate]...
In this investigation, we use the least squares type estimation to estimate the parameter a when k is known, the parameter k when a is known and to estimate the parameters a and k. Also, we evaluated the mean square errors of these estimators.A.R. Mugdadi...
Prediction error sum of squares62J05This article considers the notion of the non-diagonal-type estimator (NDTE) under the prediction error sum of squares (PRESS) criterion. First, the optimal NDTE in the PRESS sense is derived theoretically and applied to the cosmetics sales data. Second, we...
