Fisher's exact test and Pearson's chi-square with continuity correction are frequently employed in the analysis of epidemiological data involving a 2 x 2 contingency table. This paper reviews the concepts and controversies underlying these procedures and discusses their appropriateness and adequacies in analyzing such data. Other related procedures such as… (More)
This paper is a compendium of exact and asymptotic formulae and tables for estimating the sample size in a clinical trial with two treatment groups and a dichotomous outcome. The paper provides separate formulae for equal and unequal treatment group sizes, formulae for the calculation of power given the sample size, and complete references for all formulae… (More)
Some methods of constructing confidence intervals for the probability of success in a hypergeometric distribution are described and illustrated with examples. To assist the readers in implementing the procedures, pertinent information on special tables and computer programs is provided that can be readily employed with little or no additional computation.
This paper is a compendium of exact and asymptotic formulas and tables for calculating the sample size in a clinical trial for a matched-pair design involving a dichotomous outcome. Formulas for calculating power given the sample size are also given.
The purpose of this paper is to distinguish between the performance levels of the Malaysian Takaful and conventional life insurance industries with a view to better informing the decisions of stakeholders. Our analysis makes use of financial ratios and macro-economic variables namely Gross Domestic Product (GDP), Consumer Price Index (CPI) and Treasury Bill… (More)
Sulfate-reducing bacteria have been implicated in inflammatory bowel diseases and ulcerative colitis in humans and there is an interest in inhibiting the growth of these sulfide-producing bacteria. This research explores the use of several chelators of bismuth to determine the most effective chelator to inhibit the growth of sulfate-reducing bacteria. For… (More)
