  2. Law of the unconscious statistician - Wikipedia

    en.wikipedia.org/wiki/Law_of_the_unconscious...

    This proposition is (sometimes) known as the law of the unconscious statistician because of a purported tendency to think of the aforementioned law as the very definition of the expected value of of a function g(X) and a random variable X, rather than (more formally) as a consequence of the true definition of expected value.

  3. Runge–Kutta–Fehlberg method - Wikipedia

    en.wikipedia.org/wiki/Runge–Kutta–Fehlberg...

    The coefficients found by Fehlberg for Formula 1 (derivation with his parameter α 2 =1/3) are given in the table below, using array indexing of base 1 instead of base 0 to be compatible with most computer languages: The coefficients in the below table do not work.

  4. Inverse transform sampling - Wikipedia

    en.wikipedia.org/wiki/Inverse_transform_sampling

    Inverse transform sampling (also known as inversion sampling, the inverse probability integral transform, the inverse transformation method, or the Smirnov transform) is a basic method for pseudo-random number sampling, i.e., for generating sample numbers at random from any probability distribution given its cumulative distribution function.

  5. Regularized least squares - Wikipedia

    en.wikipedia.org/wiki/Regularized_least_squares

    This regularization function, while attractive for the sparsity that it guarantees, is very difficult to solve because doing so requires optimization of a function that is not even weakly convex. Lasso regression is the minimal possible relaxation of ℓ 0 {\displaystyle \ell _{0}} penalization that yields a weakly convex optimization problem.

  6. Sentence function - Wikipedia

    en.wikipedia.org/wiki/Sentence_function

    An exclamative is a sentence type in English that typically expresses a feeling or emotion, but does not use one of the other structures. It often has the form as in the examples below of [WH + Complement + Subject + Verb], but can be minor sentences (i.e. without a verb) such as [WH + Complement] How wonderful!.

  7. Catalan's constant - Wikipedia

    en.wikipedia.org/wiki/Catalan's_constant

    Catalan's constant occurs frequently in relation to the Clausen function, the inverse tangent integral, the inverse sine integral, the Barnes G-function, as well as integrals and series summable in terms of the aforementioned functions.

  8. Auxiliary function - Wikipedia

    en.wikipedia.org/wiki/Auxiliary_function

    The auxiliary function he used in the course of proving this criterion was simply the minimal polynomial of α, which is the irreducible polynomial f with integer coefficients such that f(α) = 0. This function can be used to estimate how well the algebraic number α can be estimated by rational numbers p/q.

  9. Beta-propeller - Wikipedia

    en.wikipedia.org/wiki/Beta-propeller

    Four-bladed beta-propellers function mainly as transport proteins, and because of its structure, they have a conformation that is favorable for substrate binding. [4] Unlike larger beta-propellers, four-bladed beta-propellers usually cannot perform catalysis themselves, but act instead to aid in catalysis by performing the aforementioned functions.
