Kriging with Unknown Variance Components for Regional Ionospheric Reconstruction
Ionospheric delay effect is a critical issue that limits the accuracy of precise Global Navigation Satellite System (GNSS) positioning and navigation for single-frequency users, especially in mid- and low-latitude regions where variations in the ...

Partitioning variance in reproductive success, within years and across lifetimes
Variance in reproductive success (sk2, with k = number of offspring) plays a large role in determining the rate of genetic drift and the scope within which selection acts. Various frameworks have been proposed to parse factors that contribute to sk2, but

The Variance Composition of Firm Growth Rates [PDF]
Firms exhibit a wide variability in growth rates. This can be seen as another manifestation of the fact that firms are different from one another in several respects.

An Asymmetric Area Model-Based Approach for Small Area Estimation Applied to Survey Data
The Birnbaum–Saunders distribution is asymmetrical and has received considerable attention due to its properties and its relationship with the normal distribution. In this paper, we propose a methodology for estimating the mean of small areas based on a
