Estimating the Parameters of the Latent Population Distribution

Psychometrika, 1977
Under consideration is a test battery of binary items. The responses of n individuals are assumed to follow a Rasch model. It is further assumed that the latent individual parameters are distributed within a given population in accordance with a normal distribution.

Estimation of inbreeding parameters in stratified populations

Annals of Human Genetics, 1986
SummaryA clarification is given of the differences in approaches to the estimation of F‐statistics of Nei & Chesser [Ann. Hum. Genet. (1983) 47, 253–259)] and Cockerham [Genetics (1973) 74, 679–700]. The principal difference is that Nei & Chesser define quantities with respect to fixed extant populations, while Cockerham allows for evolutionary

Parameter Estimation of the Gompertz Population

Biometrical Journal, 1997
AbstractThe Gompertz distribution has been used to model human mortality and fit actuarial tables. In the recent years, this distribution has been studied by some authors. The MLE estimates for the parameters of the Gompertz distribution were disucssed by GARG, RAO and REDMOND (1970). The purpose of this paper is to develop an exact confidence interval

Parameters for Seasonally Breeding Populations

Ecology, 1967
Lotka's equations relating the parameters of populations with no seasonal trend in birth rates and Fisher's formula for "reproductive value" are modified to describe populations with restricted annual seasons of birth. The parameters "net reproductive rate" and "mean generation length" provide statistics and dubious utility for populations with ...

Ranking of populations in parameter′s modulus

Statistics & Decisions, 2003
Summary: \textit{M. L. Eaton} [Ann. Math. Stat. 38, 124--137 (1967; Zbl 0155.25202)] successfully solved the problem of \textit{R. E. Bechhofer} [ibid. 25, 16--39 (1954; Zbl 0055.13003)] for ranking of populations based on observations of the corresponding random variables.

Bayesian Parameter Estimation and Population Pharmacokinetics

Clinical Pharmacokinetics, 1992
The widespread application of Bayesian parameter estimation in the area of therapeutic drug monitoring (TDM) has prompted the need for well conducted population studies to obtain relevant prior pharmacokinetic parameter estimates. In many cases the population has consisted of a relatively small number of subjects. This may be unavoidable for drugs used

A large population approach to estimation of parameters in Markov population models

Biometrika, 1977
SUMMARY It is known that in the limit of large population sizes certain classes of Markov population processes can be approximated by a deterministic process plus a noise term. In the usual approximation procedures the noise term is proportional to a Wiener process.

Parameter estimation of a nonlinear population model with two parameters, growth of a yeast population as an example

Ecological Modelling, 1986
Abstract Quasilinearization is a powerful numerical method used to obtain the solution of system identification problems. Its major advantages are that it is extremely accurate and quadratically convergent. In this paper, the two parameters of single logistic population are estimated using this method.

Associations of lipid parameters with insulin resistance and diabetes: A population-based study.

Clinical Nutrition, 2017
OBJECTIVE A dramatic gap exists between the clinical practice and guidelines for the dyslipidemia control in patients with diabetes. It is still uncertain which routinely available lipid measure is more applicable in estimation of insulin sensitivity and
