On Interclass and Intraclass Correlations of Familial Data with Application on Hemoglobin Level from EDHS 2000 Familial Data [PDF]
In the analysis of familial data, the primary aim is to estimate the degree of resemblance between family members. Here we are interested in the special case where one group of family members consists of one individual, as typified in the following ...

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 ...
