On parameter estimation in population models
Theoretical Population Biology, 2006We describe methods for estimating the parameters of Markovian population processes in continuous time, thus increasing their utility in modelling real biological systems. A general approach, applicable to any finite-state continuous-time Markovian model, is presented, and this is specialised to a computationally more efficient method applicable to a ...

Association of equine sperm population parameters with outcome of intracytoplasmic sperm injections.
Theriogenology, 2018Limited clinical information is available regarding sperm population parameters that are important for use with equine intracytoplasmic sperm injection (ICSI). Therefore, the appropriateness of a sample of sperm is typically not known before ICSI.

Linear estimates of a population scale parameter
Biometrika, 1967SUMMARY Downton (1966) proposed an estimator, u*, for o-, the standard deviation of a normal population. This estimator is a simple linear combination of the order statistics of a sample from the population. In the present paper, four moments of o-* are given in closed form and the use of Y = (,c6-,uO)/o* is investigated as a possible competitor to the

Parameter-less population pyramid with feedback
Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2017The Parameter-less Population Pyramid (P3) is a recent method proposition that includes the linkage learning mechanisms based on the Dependency Structure Matrix (DSM) clustering. P3 was shown to be effective for solving various hard theoretical problems.

Estimating the Parameter of a Selected Population
Calcutta Statistical Association Bulletin, 1995Suppose independent samples from k populations with unknown parameters are taken and one of the populations is selected based on tho data and a prespecified rule. The problem is to estimate the parameter of the selected population. The estimand, G, is a random quantity which depends on both the data and the unknown parameters. While standard estimation
