“To Randomize, or Not to Randomize, That is the Question”

Arthritis & Rheumatology, 2021
Until the end of the last century there were no drugs approved for the treatment of juvenile idiopathic arthritis (JIA). This situation was revolutionized in the past 20 years thanks to 3 factors: the introduction in the USA and in Europe of paediatric legislations(1, 2), the availability of biologic disease-modifying anti-rheumatic drugs (b-DMARDs ...

Random Relations, Random Utilities, and Random Functions

Journal of Mathematical Psychology, 2001
The aim of the paper is to extend the first author's earlier results, and to complement and reformulate closely related work, by analyzing the relationship between three fundamental ways of mathematically representing judgements and preferences. The paper significantly extends the following three approaches considered in the paper to modelling the ...

Random Thoughts on Randomization

JAMA: The Journal of the American Medical Association, 1978
In their informative assessment of 13 years of aortocoronary bypass surgery, DeBakey and Lawrie (p 837), dispute the necessity of prospective randomized studies for the evaluation of surgical diagnostic and therapeutic techniques. They point out that certain time-honored criteria, particularly clinical experience, have proved reliable in assessing ...

Random Walks on Random Graphs

2009
The aim of this article is to discuss some of the notions and applications of random walks on finite graphs, especially as they apply to random graphs. In this section we give some basic definitions, in Section 2 we review applications of random walks in computer science, and in Section 3 we focus on walks in random graphs.

Randomization Among: The Other Randomization

Ethics & Human Research, 2019
ABSTRACTA valid informed consent process for a randomized controlled trial requires the disclosure to potential participants that they will be randomized to receive the study intervention or a control intervention. This is a case of randomizationwithina trial, a type of randomization that has received significant attention in research ethics.

“Random” random matrix products

Journal d'Analyse Mathématique, 2001
This paper studies compositions of independent random bundle maps \(F(x,a)=f_Fx,T_F(x)a\), \(x\in X\), \(a\in \mathbb R^d\), where \(X\) is a Borel subset of a Polish space, whose distributions form a stationary process. This specializes to the case of products of independent random matrices evolving by a stationary process and generalizes many results

Random Multiclass Classification: Generalizing Random Forests to Random MNL and Random NB [PDF]

, 2007
Random Forests (RF) is a successful classifier exhibiting performance comparable to Adaboost, but is more robust. The exploitation of two sources of randomness, random inputs (bagging) and random features, make RF accurate classifiers in several domains.

Local Randomness in Polynomial Random Number and Random Function Generators

SIAM Journal on Computing, 1993
Summary: A distribution on \(n\)-bit strings is called \((\varepsilon,e)\)-locally random, if for every choice of \(e \leq n\) positions the induced distribution on \(e\)-bit strings is in the \(L_ 1\)-norm at most \(\varepsilon\) away from the uniform distribution on \(e\)-bit strings. Local randomness in polynomial random number generators (RNG) that
