Power analysis for stepped wedge trials with multiple interventions
Sign Up to like & getrecommendations! Published in 2022 at "Statistics in Medicine"
DOI: 10.1002/sim.9301
Abstract: Stepped wedge design (SWD) trials are cluster randomized trials that feature staggered, unidirectional crossâover between treatment conditions. Existing literature on power for SWDs focuses primarily on designs with two conditions, typically a control and an… read more here.

DOI: 10.1016/j.petrol.2018.08.068
Abstract: Abstract An all too often question when designing field trials aimed at the validation of EOR techniques is how long the stimulation should last. In these trials, the stimulation period is proportional to the trial… read more here.

DOI: 10.1037/met0000330
Abstract: This article proposes a summary-statistics-based power analysis-a practical method for conducting power analysis for mixed-effects modeling with two-level nested data (for both binary and continuous predictors), complementing the existing formula-based and simulation-based methods. The proposed… read more here.

DOI: 10.1037/met0000684
Abstract: It is unappreciated that there are four different approaches to power analysis for detecting misspecification by testing overall fit of structural equation models (SEMs) and, moreover, that common approaches can yield radically diverging results for… read more here.

DOI: 10.1038/s41437-019-0205-3
Abstract: Power calculation prior to a genetic experiment can help investigators choose the optimal sample size to detect a quantitative trait locus (QTL). Without the guidance of power analysis, an experiment may be underpowered or overpowered.… read more here.

DOI: 10.1080/00273171.2018.1557032
Abstract: Power analysis is the gold standard for justifying sample size in study design. Extant software for computing power (e.g., G Power by Faul, Erdfelder, Buchner, & Lang, 2009) can only accept the specification of a… read more here.
