What use are Exponential Weights for flexi-Weighted Least Squares Phylogenetic Trees?
Exponential Weights flexi-Weighted Least Squares Phylogenetic Trees
2011/1/5
The method of flexi-Weighted Least Squares on evolutionary trees uses simple polynomial or exponential functions of the evolutionary distance in place of model-based variances. This has the advantage ...
Auto Regressive Model and Weighted Least Squares Based Packet Video Error Concealment
Auto Regressive Model Weighted Least Squares Video Error Concealment
2010/12/21
In this paper, auto regressive (AR) model is applied to error concealment for block-based
packet video encoding. Each pixel within the corrupted block is restored as the weighted
summation of corres...
Weighted least-squares estimators of tail indices
Weighted least-squares estimators tail indices
2009/9/22
We propose a class of weighted least-squares estimators
for the tail index of a regularly varying upper tail of a distribution.
Universal asymptotic normality of the estimators is established over

Weighted least squares methods for prediction in the functional data linear model
Cross-validation eigenfunction eigenvector functional data analysis mean squared error orthogonal series rate of convergence
2009/9/16
The problem of prediction in functional linear regression is conventionally addressed by reducing dimension via the standard principal component basis. In this paper we show that weighted least-square...
