Description
Need to allocate subjects to a clinical trial at random and still ahve equal n umbers in each group? This app allows that and also stores the data you want to collect.
This application ensures that there will be equal numbers of interventions in any subgroup that is designated. There can be any number of observations, ups to five interventions and five subgroups. The application does all the hard work of distributing subjects at random across subgroup, with equal numbers allotted to each treatment arm.
Each subgroup has a different order of randomized allocations.
Professor Rand Wilcox of the University of Southern California (Author of "Introduction to Robust Estimation and Hypothesis Testing. A volume in Statistical Modeling and Decision Science") says: "Looks like a very convenient and useful tool."
The 5th edition of his book is due out around November 2021.
Commercial companies charge thousands of dollars to randomize data. (For example, see https://randomize.net/#pricing) Of course, they may offer many additional features, but why pay this amount for such a simple task when using this application?
What’s New
Version 2.8
