groups. From a review of the literature and from their own clinical experience, the investigators anticipate approximately 50% of the women with a regular training program will suffer an ACL tear. They hypothesize that a reduction by one-half, resulting in only a 25% incidence in ACL injuries in the hamstrings training group, would be a clinically significant finding. The investigators set their

Sample size determination for logistic regression
The problem of sample size estimation is important in medical applications, especially in cases of expensive measurements of immune biomarkers. This paper describes the problem of logistic regression analysis with the sample size determination algorithms, namely the methods of univariate statistics, logistics regression, cross-validation and Bayesian inference. The authors, treating the regr...
متن کاملRAPD Analysis for Sex Determination in Pistacia vera L.
Random Amplified Polymorphic DNA (RAPD) analysis of Pistacia vera L. was used to distinguishing sex type in progeny plants. Varied genotypes of the pistachio were analyzed by PCR amplification of a ten base primer previously found to be linked to the expression of a 945bp amplification band in female trees and its absence in males. Results revealed that genetic material from cultivar samples am...
متن کاملBayesian Sample size Determination for Longitudinal Studies with Continuous Response using Marginal Models
Introduction Longitudinal study designs are common in a lot of scientific researches, especially in medical, social and economic sciences. The reason is that longitudinal studies allow researchers to measure changes of each individual over time and often have higher statistical power than cross-sectional studies. Choosing an appropriate sample size is a crucial step in a successful study. A st...
متن کاملSample size determination for quadratic inference functions in longitudinal design with dichotomous outcomes.
Quadratic inference functions (QIF) methodology is an important alternative to the generalized estimating equations (GEE) method in the longitudinal marginal model, as it offers higher estimation efficiency than the GEE when correlation structure is misspecified. The focus of this paper is on sample size determination and power calculation for QIF based on the Wald test in a marginal logistic m...
متن کاملBayesian Determination of Sample Size in Longitudinal Studies with Binary Responses Using Random Effects Models
Sample size determination is important in all statistical studies including longitudinal studies. This is usually done by considering a target power to reduce the costs of sampling. Choosing the right sample size using efficient methods, ensures that the researcher achieve goal of the study, by spending the least amount of energy, time and money. In this article, using a method based on simulat...
