The modelling of prey–predator interactions is of major importance for the understanding of population dynamics. Classically, these interactions are modelled using ordinary differential equations, but this approach has the drawbacks of assuming continuous population variables and of being deterministic. We propose a general approach to stochastic modelling based on the concept of functional...

Reliable confidence intervals in quantitative genetics: narrow-sense heritability

Fabbro, Thomas ; Davison, Anthony C. ; Steinger, Thomas

In: Theoretical and Applied Genetics, 2008, vol. 115, no. 7, p. 933-944

Many quantitative genetic statistics are functions of variance components, for which a large number of replicates is needed for precise estimates and reliable measures of uncertainty, on which sound interpretation depends. Moreover, in large experiments the deaths of some individuals can occur, so methods for analysing such data need to be robust to missing values. We show how confidence...
