Design-based random permutation models with auxiliary information
(TAYLOR & FRANCIS LTDABINGDON, 2012)
We extend the random permutation model to obtain the best linear unbiased estimator of a finite population mean accounting for auxiliary variables under simple random sampling without replacement (SRS) or stratified SRS. ...
Systematic sequencing of factorial experiments as an alternative to the random order
(2017-01-01)
The current study aims to discuss the use of systematic methods to generate experimental designs with good statistical properties and low costs. The research focuses on the sequence of experiments and on analysis the results ...
Randomized trials published in higher vs lower impact journals differ in design, conduct, and analysis
(Elsevier, 2013)
To compare methodological characteristics of randomized controlled trials (RCTs) published in higher vs. lower impact Core Clinical Journals.
Initiation and continuation of randomized trials after the publication of a trial stopped early for benefit asking the same study question: STOPIT-3 study design
(BioMed Central, 2013)
Background: Randomized control trials (RCTs) stopped early for benefit (truncated RCTs) are increasingly common and, on average, overestimate the relative magnitude of benefit by approximately 30%. Investigators stop trials ...
Mixed two- and four-level experimental designs for interchangeable parts with different degrees of assembly difficulty
(International journal of quality & reliability management, 2017-08)
Eficiencia relativa del diseño de bloques completos al azar para ensayos de arroz en Bagaces, Guanacaste, Costa Rica
(2015)
La elección de un diseño experimental adecuado es uno de los aspectos de mayor importancia en investigación científica. Existen varios tipos de diseño experimental que se pueden emplear según sean las condiciones del entorno ...
Statistical moments of the solution of the random Burgers-Riemann problem
(Elsevier Science BvAmsterdamHolanda, 2009)
Virando latas e colorindo superfícies: projeto de estampas têxteis inspiradas em cães sem raça definida
(Universidade Federal de Santa MariaBrasilUFSMCentro de Artes e Letras, 2019-12-05)
This monograph aims to create a fabric pattern collection inspired by random breed dogs. In the area of Surface Design, the textile segment is chosen for practical development of this research. Among the many possibilities ...
Randomized controlled trials for COVID-19: evaluation of optimal randomization methodologies - need for the data validation of the completed trials, and to improve the ongoing and future randomized trial designs
COVID-19. The Recovery trials showed an Absolute Risk Reduction (ARR) in mortality by 2.8% with
Dexamethasone, and the ACTT-1 trial showed that the treatment with Remdesivir reduced the Time to
recovery by 4 days. The ...
