Estimating population birth rates of zooplankton when rates of egg deposition and hatching are periodic

Mutation rates: estimating phase variation rates when fitness differences are present and their impact on population structure.

Phase variation is a mechanism of ON-OFF switching that is widely utilized by bacterial pathogens. There is currently no standardization to how the rate of phase variation is determined experimentally, and traditional methods of mutation rate estimation may not be appropriate to this process. Here, the history of mutation rate estimation is reviewed, describing the existing methods available. A...

Estimating recombination rates from population genetic data.

We introduce a new method for estimating recombination rates from population genetic data. The method uses a computationally intensive statistical procedure (importance sampling) to calculate the likelihood under a coalescent-based model. Detailed comparisons of the new algorithm with two existing methods (the importance sampling method of Griffiths and Marjoram and the MCMC method of Kuhner an...

Estimating multistate transition rates from population distributions

The ability to estimate interstate transition rates (or probabilities) from population distributions has many potential applications in demography. Iterative Proportional Fitting (IPF) has been used for such estimation, but lacks a meaningful behavioral foundation. Here a new approach, Relative State Attraction (RSA), is advanced. It assumes that states have a greater (or lesser) ability to att...

The effect of twin birth on neonatal and infant mortality rates: A systematic review

Background: Twin birth may account for a higher incidence rates of infants and neonates. To investigate the potential relationship between twin birth and infant and neonatal mortality rates, a systematic review was conducted.Methodology: To gather the evidence for the relationship between twin birth and its potential effect on mortality during infancy and neonatal periods, a systematic re...
