Methods of variance component estimation
Estimation of variance components is a method often used in population genetics and applied in animal breeding. Even experienced population geneticists nowadays feel lost if confronted with the huge set of different methods of variance component ...

ACCURACY ANALYSIS OF HRSI-BASED GEOPOSITIONING USING LEAST SQUARES COLLOCATION [PDF]
Rational function model with bias compensation has been widely used in geopositioning of High Resolution Satellite Imagery (HRSI). We studied the geopositioning issue using a pair of QuickBird imagery in the Shanghai urban area with 126 Control Points (

The Impact of Noise in a GRACE/GOCE Global Gravity Model on a Local Quasi‐Geoid
Abstract We present a local quasi‐geoid (QG) model which combines a satellite‐only global gravity model with local data sets using weighted least squares. The QG is computed for an area comprising the Netherlands, Belgium, and the southern North Sea. It uses a two‐scale spherical radial basis function model complemented by bias parameters to account ...

The use of global navigation satellite system (GNSS) is entering a new era of joint positioning based on the use of multifrequencies and multimodes. Ensuring the correct weighting of observations from each system and satellite has become a key problem during real‐time positioning. This paper addresses the issue of weights of observations as well as the

Analysis of epistasis: A genetic model for triploid endosperm traits
A genetic model for triploid endosperm traits was proposed on the basis of diallel cross system to analyze additive by additive epistasis of direct effect (AA) and maternal effect (AmAm) along with direct additive effect, dominance effect, cytoplasm ...

Analysis of Combined Experiments Revisited
Agronomic experiments are often replicated over time and space to evaluate how treatments perform across a range of environments. The analysis of experiments conducted for more than one growing season (years) and/or places (locations) is commonly referred to as analysis of combined experiments.

Computation of variance components by the MINQUE method
We present a new method of computing C. R. Rao's MINQUE in variance component models \((y=X\beta +U_ 1\xi_ 1+\cdots +U_ p\xi_ p)\), which requires only inversion and storage of \(n_ i\times n_ i\) matrices, where \(n_ i\) is the number of columns in \(U_ i\). In many cases most of these matrices are of diagonal form.

A Strategy for Finding the Optimal Scale of Plant Core Collection Based on Monte Carlo Simulation
Core collection is an ideal resource for genome‐wide association studies (GWAS). A subcore collection is a subset of a core collection. A strategy was proposed for finding the optimal sampling percentage on plant subcore collection based on Monte Carlo simulation.
