Sample Size Determination for Some Common Nonparametric Tests
TLDR
In this article, the problem of determining the number of observations required by some common nonparametric tests, so that the tests have power at least 1 − β against alternatives that differ sufficiently from the hypothesis being tested is discussed.Abstract:
The article discusses the problem of determining the number of observations required by some common nonparametric tests, so that the tests have power at least 1 – β against alternatives that differ sufficiently from the hypothesis being tested. It is shown that the number of observations depends on certain simple probabilities. A method is suggested for fixing the value of the appropriate probability when determining sample size.read more

A study on the use of non-parametric tests for analyzing the evolutionary algorithms' behaviour: a case study on the CEC'2005 Special Session on Real Parameter Optimization
TL;DR: This study analyzes the published results for the algorithms presented in the CEC’2005 Special Session on Real Parameter Optimization by using non-parametric test procedures and states that a parametric statistical analysis could not be appropriate specially when the authors deal with multiple-problem results.

TL;DR: In a placebo-controlled trial, treatment with natalizumab led to fewer inflammatory brain lesions and fewer relapses over a six-month period in patients with relapsing multiple sclerosis.

Distribution-free and robust statistical methods: viable alternatives to parametric statistics?
Catherine Potvin,Derek A. Roff +1 more
TL;DR: This paper attempts to introduce some distribution-free and robust techniques to ecologists and to offer a critical appraisal of the potential advantages and drawbacks of these methods.

High-flow oxygen therapy in acute respiratory failure.
TL;DR: HFNC was better tolerated and more comfortable than face mask and was associated with better oxygenation and lower respiratory rate, which could have an important role in the treatment of patients with acute respiratory failure.

TL;DR: In this paper, a method has been described in which flows of up to 50 L/min are delivered through a nasal cannula with a heated humidifier that optimizes oxygen administration.
