  2. Phi coefficient - Wikipedia

    en.wikipedia.org/wiki/Phi_coefficient

    In statistics, the phi coefficient (or mean square contingency coefficient and denoted by φ or r φ) is a measure of association for two binary variables.. In machine learning, it is known as the Matthews correlation coefficient (MCC) and used as a measure of the quality of binary (two-class) classifications, introduced by biochemist Brian W. Matthews in 1975.

    Phi value analysis assumes Hammond's postulate, which states that energy and chemical structure are correlated.Though the relationship between the folding intermediate and native state's structures may correlate that between their energies when the energy landscape has a well-defined, deep global minimum, free energy destabilizations may not give useful structural information when the energy ...

    The 2018 Verizon Protected Health Information Data Breach Report (PHIDBR) examined 27 countries and 1368 incidents, detailing that the focus of healthcare breaches was mainly the patients, their identities, health histories, and treatment plans. According to HIPAA, 255.18 million people were affected from 3051 healthcare data breach incidents ...

  5. Effect size - Wikipedia

    en.wikipedia.org/wiki/Effect_size

    In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...

    Phi; the symbol used for integrated information. Integrated information theory (IIT) proposes a mathematical model for the consciousness of a system. It comprises a framework ultimately intended to explain why some physical systems (such as human brains) are conscious, [1] and to be capable of providing a concrete inference about whether any physical system is conscious, to what degree, and ...

    Quantum state tomography is a process by which, given a set of data representing the results of quantum measurements, a quantum state consistent with those measurement results is computed. [50] It is named by analogy with tomography , the reconstruction of three-dimensional images from slices taken through them, as in a CT scan .
