A comparative study of restricted randomization procedures for multiarm trials with equal or unequal treatment allocation ratios

Statistics in Medicine, 2018
Randomization designs for multiarm clinical trials are increasingly used in practice, especially in phase II dose‐ranging studies. Many new methods have been proposed in the literature; however, there is lack of systematic, head‐to‐head comparison of the

RESTRICTED RANDOM TESTING: ADAPTIVE RANDOM TESTING BY EXCLUSION

International Journal of Software Engineering and Knowledge Engineering, 2006
Restricted Random Testing (RRT) is a new method of testing software that improves upon traditional Random Testing (RT) techniques. Research has indicated that failure patterns (portions of an input domain which, when executed, cause the program to fail or reveal an error) can influence the effectiveness of testing strategies.

Restricted stratified random sampling

International Journal of Mineral Processing, 1989
Abstract A method of sampling is described which is a compromise between systematic sampling and stratified random sampling. It has less potential for bias than systematic sampling and also avoids the practical problems associated with stratified random sampling.

Restricted Random Testing

2002
This paper presents a novel adaptation of traditional random testing, called Restricted Random Testing (RRT). RRT offers a significant improvement over random testing, as measured by the F-measure. This paper describes the ideology behind RRT and explains its algorithm.

LIMIT SETS OF RESTRICTED RANDOM SUBSTITUTIONS

Fractals, 2006
We consider a certain type of random substitution and show that the sets generated by it have almost surely the same box-counting and Hausdorff dimension, and that box-counting and Hausdorff dimension coincide.

Randomization tests for restricted alternating treatments designs.

Behaviour Research and Therapy, 1994
Alternating Treatments Designs (ATD) with random assignment of the treatments to the measurement times provide very powerful single-case experiments. However, complete randomization might cause too many consecutive administrations of the same treatment to occur in the design. In order to exclude these possibilities, an ATD with restricted randomization

Restricted Random Reinforcement in Probability Learning

Psychological Reports, 1965
An exact frequency ratio of 3:1 was maintained between reinforcing events over successive blocks of 4, 8, 16, or 128 trials in a two-choice verbal conditioning situation. No effect of such restricted randomization was found upon the mean learning curves, total number of responses, or variance in total number of responses.

Normalized Restricted Random Testing

2003
Restricted Random Testing (RRT) is a new method of testing software that improves upon traditional random testing (RT) techniques. This paper presents new data in support of the efficiency of RRT, and presents a variation of the algorithm, Normalized Restricted Random Testing (NRRT).
