Overview of Friedman’s Test and Post-hoc Analysis
Communications in Statistics - Simulation and Computation, 2014When the null hypothesis of Friedman’s test is rejected, there is a wide variety of multiple comparisons that can be used to determine which treatments differ from each other. We will discuss the contexts where different multiple comparisons should be applied, when the population follows some discrete distributions commonly used to model count data in ...

The Value of a Post Hoc Power Analysis
The Journal of Bone & Joint Surgery, 2002To The Editor: I am writing in regard to "Type-II Error Rates (Beta Errors) of Randomized Trials in Orthopaedic Trauma" (2001;83:1650-5), by Lochner et al. This paper addresses a very important issue, namely, that of designing studies that have adequate statistical power to detect clinically meaningful differences.

Chest, 2014
I am surprised by the published conclusions of Hung et al 1 in a recent issue of CHEST (August 2013). The authors’ stated meth ods are not adequate to support their conclusion that hyperimmune IV immunoglobulin (H-IVIG) ben efi ts mortality if given within 5 days to patients with severe 2009 infl uenza A(H1N1) infection. The primary outcome analysis of

Post hoc tests following analysis of variance
Research in Nursing & Health, 1985AbstractReview of nursing research literature revealed that post hoc comparisons of mean differences were not consistently reported, although their use was warranted. This paper describes the critical features of post hoc procedures and offers guidelines for selecting one method over another.

A Proposal for Post Hoc Subgroup Analysis in Support of Regulatory Submission
Therapeutic Innovation & Regulatory Science, 2022In clinical trials, it is not uncommon that the primary analysis fails to achieve the study objective for demonstrating the safety and efficacy of a test treatment under investigation, while a specific sub-population analysis shows a significant positive result.

Journal of Applied Psychology, 1994
The objective of a post hoc review of statistical power is to determine the average power of tests used in a particular field. Because most theories in psychology are not sufficiently advanced to provide an exact prediction of effect size, post hoc reviews invariably calculate the power of a test in terms of the test's ability to detect the expected ...

Post hoc analysis of sport performance with differential evolution
Neural Computing and Applications, 2018Advising athletes how to improve their performance after a race is a very important aspect of sport training. It can also be called a post hoc analysis, which often includes a deep analysis of an athlete’s performance, behavior and body characteristics after a race.

Febuxostat and renal outcomes: post-hoc analysis of a randomized trial
Hypertension Research, 2023Effect of urate-lowering on renal outcomes in patients at high-risk for cardiovascular disease with hyperuricemia without gout is not known. We conducted a post hoc analysis of a randomized trial (Febuxostat for Cerebral and CaRdiorenovascular Events PrEvEntion StuDy [FREED]).

A Note on Post Hoc Analysis of Mastery Test Data
Journal of Learning Disabilities, 1986This note suggests a post hoc analysis procedure for use with the type of data likely in mastery testing-skewed, non-normal in distribution with a truncated range. It is suggested that various characteristics of the data be examined if analysis using parametric multivariate techniques is conducted.

A new approach to post-hoc problem in cluster analysis
Model Assisted Statistics and Applications, 2012Suppose that a cluster partition of some finite set is constructed using several given characteristics of the set elements. Our aim is to arrange these characteristics in descending order with a respect to the strength of their influence on the cluster structure.
