The Rand index [1] or Rand measure (named after William M. Rand) in statistics, and in particular in data clustering, is a measure of the similarity between two data clusterings. A form of the Rand index may be defined that is adjusted for the chance grouping of elements, this is the adjusted Rand index .
James Randi (born Randall James Hamilton Zwinge; August 7, 1928 – October 20, 2020) was a Canadian-American stage magician, author, and scientific skeptic who extensively challenged paranormal and pseudoscientific claims. [1]
It corrects the effect of agreement solely due to chance between clusterings, similar to the way the adjusted rand index corrects the Rand index. It is closely related to variation of information: [2] when a similar adjustment is made to the VI index, it becomes equivalent to the AMI. [1] The adjusted measure however is no longer metrical. [3]
MATLAB (an abbreviation of "MATrix LABoratory" [22]) is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks.MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.
Reasonable and non-discriminatory (RAND) terms, also known as fair, reasonable, and non-discriminatory (FRAND) terms, denote a voluntary licensing commitment that standards organizations often request from the owner of an intellectual property right (usually a patent) that is, or may become, essential to practice a technical standard.

Later, Lexington Broadcasting wanted Randi to do a show called the $100,000 Psychic Prize, so they added $90,000 to the original $10,000 raised by Randi. Finally, in 1996, one of his friends, Internet pioneer Rick Adams, donated $1 million for the prize. [7] The prize is sometimes referred to in the media as the "Randi Prize".
Simulink is a MATLAB-based graphical programming environment for modeling, simulating and analyzing multidomain dynamical systems. Its primary interface is a graphical block diagramming tool and a customizable set of block libraries. It offers tight integration with the rest of the MATLAB environment and can either drive MATLAB or be scripted ...
Project Alpha was an effort by magician James Randi to test the quality of scientific rigor of a well-known test of paranormal phenomena.. In the late 1970s, Randi contacted the newly established McDonnell Laboratory for Psychical Research ("MacLab") with suggestions on how to conduct tests for paranormal phenomena.
