ADMISSIBLE ESTIMATORS OF DISCRIMINANT COEFFICIENTS

Statistics & Risk Modeling, 1991
Summary: On the basis of a multivariate normal observation with an unknown mean \(\xi\) and a covariance matrix of the form \(\sigma^ 21\), the estimation problem of the vector \(\sigma^{-2}\xi\) is considered. For a quadratic loss a necessary and sufficient condition for the admissibility of a natural estimator is obtained.

Estimation of Diffusion Coefficients in Biomembranes

Journal of Colloid and Interface Science, 2000
In this paper, the determination of diffusion coefficients in plant biomembranes for the nonstationary diffusion state is discussed. It is suggested that any point in the heterogeneous structures may be considered to be in Donnan equilibrium with a given external salt concentration.

Estimation of rate coefficients

1971
The choice of an appropriate method for estimating a rate coefficient is dictated largely by the behaviour of the reaction system and the experimental procedures adopted for its study. Reliable results are usually the outcome of sensible planning of experiments, and, in this respect material balance graphs, such as those outlined in Chapter 3, can ...

Estimated coefficients and inference

2014
An introductory section shows the behavior of quantile regressions in datasets with different characteristics, adding more details to the discussion developed in Section 2.2. Section 3.2, using simulated data, shows the empirical distribution of the quantile regression estimator in case of independent and identically distributed (i.i.d.) errors, in ...
