Unbiased estimator for genetic drift and effective population size.
Amounts of genetic drift and the effective size of populations can be estimated from observed temporal shifts in sample allele frequencies. Bias in this so-called temporal method has been noted in cases of small sample sizes and when allele frequencies are highly skewed. We characterize bias in commonly applied estimators under different sampling plans and propose an alternative estimator for g...
متن کاملExposing Hidden Performance Opportunities in High Performance GPU Applications
The emergence of leadership class systems with nodes containing many-core accelerators, such as GPUs, has the potential to vastly increase the performance of distributed applications. Exploiting the additional parallelism that manycore accelerators offer is fraught with challenges. Developers and existing performance tools focus on a subset of these challenges, primarily the identification of C...
متن کاملThe Minimum Variance Unbiased Estimator
This module motivates and introduces the minimum variance unbiased estimator (MVUE). This is the primary criterion in the classical (frequentist) approach to parameter estimation. We introduce the concepts of mean squared error (MSE), variance, bias, unbiased estimators, and the bias-variance decomposition of the MSE. The Minimum Variance Unbiased Estimator 1 In Search of a Useful Criterion In ...
متن کاملPopulation Attributable Risk (PAR) of Cardiovascular Diseases (CVD) Risk Factors; Bayesian Methods
Background & Objective: Cardiovascular disease (CVD) is the main cause of morbidity and mortality in most countries. By identifying the population attributable risk (PAR) of the main risk factors of CVDs, the overall effect of various exposures on a population can be determined; the findings could be used in CVD prevention. The present study aimed to explore the PAR of some factors, includin...
متن کاملHigh Proportion of Male Faeces in Jaguar Populations
Faeces provide relevant biological information which includes, with the application of genetic techniques, the sex and identity of individuals that defecated, thus providing potentially useful data on the behaviour and ecology of individuals, as well as the dynamics and structure of populations. This paper presents estimates of the sex ratio of different felid species (jaguar, Panthera onca; pu...
متن کاملStein Unbiased GrAdient estimator of the Risk (SUGAR) for Multiple Parameter Selection
Algorithms to solve variational regularization of ill-posed inverse problems usually involve operators that depend on a collection of continuous parameters. When these operators enjoy some (local) regularity, these parameters can be selected using the socalled Stein Unbiased Risk Estimate (SURE). While this selection is usually performed by exhaustive search, we address in this work the problem...
