Sample size calculation in epidemiological studies
Sample-size determination is often an important step in planning an epidemiological study. There are several approaches to determining sample size. It depends on the type of the study. Descriptive, observational and randomized controlled studies have different formulas to calculate sample size. In this article, we discuss the formulas that can help to estimate sample size in an epidemiological ...
متن کاملBayesian sample size determination for estimating binomial parameters from data subject to misclassification
We investigate the sample size problem when a binomial parameter is to be estimated, but some degree of misclassification is possible. The problem is especially challenging when the degree to which misclassification occurs is not exactly known. Motivated by a Canadian survey of the prevalence of toxoplasmosis infection in pregnant women, we examine the situation where it is desired that a margi...
متن کاملSample Size Calculation for Comparing Time-to-event Data
In clinical research, the occurrence of certain events (e.g., adverse events, disease progression, relapse, or death) is often of particular interest to the investigators, especially in the area of cancer trials. In most situations, these events are undesirable and unpreventable. In practice, it would be beneficial to patients if the test treatment could delay the occurrence of such events. As ...

متن کاملSample Size Calculation for Comparing Means
Sample size calculation plays an important role in clinical research. In clinical research, a sufficient number of patients is necessary to ensure the validity and the success of an intended trial. From a statistical point of view, if a clinically meaningful difference between a study treatment and a control truly exists, such a difference can always be detected with an arbitrary power as long ...
