Population diversity index

Proceedings of the 13th annual conference companion on Genetic and evolutionary computation, 2011
A number of diversity measures used in evolutionary computing suffer from 'mis-measuring' the diversity of populations. In this paper, we identify and demonstrate this problem using a carefully engineered test suite of six differently arranged populations.

Multistage Index Selection in Finite Populations

Biometrics, 1991
Multistage selection with fixed proportions and selection indices based on covariates of the target variable is studied. Assuming a multivariate normal distribution before the selection, expressions are presented for the expectation and the variance of the target variable in the retained subpopulation. As the numerical evaluation for finite populations

On Smoothing Trends in Population Index Modeling

Biometrics, 2007

We use a state–space modeling approach within a Bayesian framework to describe population level trends over time and contribute to the alert system used by the British Trust for Ornithology.
