  2. Frequentist probability - Wikipedia

    en.wikipedia.org/wiki/Frequentist_probability

    John Venn, who provided a thorough exposition of frequentist probability in his book, The Logic of Chance. [1]Frequentist probability or frequentism is an interpretation of probability; it defines an event's probability as the limit of its relative frequency in infinitely many trials (the long-run probability). [2]

  3. Stochastic ordering - Wikipedia

    en.wikipedia.org/wiki/Stochastic_ordering

    Downward-lexicographic dominance, denoted , means that has a larger probability than of returning the best outcome, or both and have the same probability to return the best outcome but has a larger probability than of returning the second-best best outcome, etc. Upward-lexicographic dominance is defined analogously based on the probability to ...

  4. Nonprobability sampling - Wikipedia

    en.wikipedia.org/wiki/Nonprobability_sampling

    Deviant case: The researcher obtains cases that substantially differ from the dominant pattern. The case is selected in order to obtain information on unusual cases that can be specially problematic or specially good. Case study: The research is limited to one group, often with a similar characteristic or of small size. Quota sampling.

  5. Stochastic dominance - Wikipedia

    en.wikipedia.org/wiki/Stochastic_dominance

    Stochastic dominance is a partial order between random variables. [1] [2] It is a form of stochastic ordering.The concept arises in decision theory and decision analysis in situations where one gamble (a probability distribution over possible outcomes, also known as prospects) can be ranked as superior to another gamble for a broad class of decision-makers.

  6. Imprecise probability - Wikipedia

    en.wikipedia.org/wiki/Imprecise_probability

    Uncertainty is traditionally modelled by a probability distribution, as developed by Kolmogorov, [1] Laplace, de Finetti, [2] Ramsey, Cox, Lindley, and many others.However, this has not been unanimously accepted by scientists, statisticians, and probabilists: it has been argued that some modification or broadening of probability theory is required, because one may not always be able to provide ...

  7. Monty Hall problem - Wikipedia

    [50] [13] [49] The conditional probability of winning by switching is ⁠ 1/3 / 1/3 + 1/6 ⁠, which is ⁠ 2 / 3 ⁠. [2] The conditional probability table below shows how 300 cases, in all of which the player initially chooses door 1, would be split up, on average, according to the location of the car and the choice of door to open by the host.

  8. Noncentral F-distribution - Wikipedia

    en.wikipedia.org/wiki/Noncentral_F-distribution

    In probability theory and statistics, the noncentral F-distribution is a continuous probability distribution that is a noncentral generalization of the (ordinary) F-distribution. It describes the distribution of the quotient ( X / n 1 )/( Y / n 2 ), where the numerator X has a noncentral chi-squared distribution with n 1 degrees of freedom and ...

  9. Influence of nonstandard analysis - Wikipedia

    en.wikipedia.org/wiki/Influence_of_nonstandard...

    "Radically elementary probability theory" of Edward Nelson combines the discrete and the continuous theory through the infinitesimal approach. [citation needed] [1] The model-theoretical approach of nonstandard analysis together with Loeb measure theory allows one to define Brownian motion as a hyperfinite random walk, obviating the need for cumbersome measure-theoretic developments.
