Estimation of Variance Components for Body Weight of Moghani Sheep Using B-Spline Random Regression Models
The aim of the present study was the estimation of (co) variance components and genetic parameters for body weight of Moghani sheep, using random regression models based on B-Splines functions. The data set included 9165 body weight records from 60 to 360 days of age from 2811 Moghani sheep, collected between 1994 to 2013 from Jafar-Abad Animal Research and Breeding Institute, Ardabil province,...
متن کاملVariance Estimation for Tree Order Restricted Models
In this article we discuss estimation of the common variance of several normal populations with tree order restricted means. We discuss the asymptotic properties of the maximum likelihood estimator of the variance as the number of populations tends to infinity. We consider several cases of various orders of the sample sizes and show that the maximum likelihood estimator of the variance may or m...
متن کاملConditionally Gaussian Random Sequences for Robust Integrated Variance Estimation
Conditionally Gaussian random sequences generalize State Space models along two relevant directions: (a) the parameters of the model depend in an arbitrary way from past observations, but once this dependence is realized, the randomness can be expressed in terms of Gaussian random variables, (b) correlation is introduced between the transition and measurement equations, through the presence of ...
متن کاملEstimation of population variance in successive sampling
This paper proposes a class of estimators of finite population variance in successive sampling on two occasions and analyzes its properties. Isaki (J Am Stat Assoc 78:117– 123, 1983) motivated to consider the problem of estimation of finite population variance in survey sampling, and its extension to the case of successive sampling is much interesting, and the theory developed here will be help...
