  2. 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 ...

  6. Eta and eta prime mesons - Wikipedia

    en.wikipedia.org/wiki/Eta_and_eta_prime_mesons

    The eta (η) and eta prime meson (η′) are isosinglet mesons made of a mixture of up, down and strange quarks and their antiquarks. The charmed eta meson (η c) and bottom eta meson (η b) are similar forms of quarkonium; they have the same spin and parity as the (light) η defined, but are made of charm quarks and bottom quarks respectively.

  9. Dedekind eta function - Wikipedia

    en.wikipedia.org/wiki/Dedekind_eta_function

    Take a modular form f with weight k that is not in the span of our computed eta quotients, and compute f η g as a linear combination of eta-quotients in M k ′ (Γ 0 (N)) and then divide out by η g. The result will be an expression of f as a linear combination of eta quotients as desired. Repeat this until a basis is formed.
