  2. Rao–Blackwell theorem - Wikipedia

    en.wikipedia.org/wiki/Rao–Blackwell_theorem

    In the most frequently cited examples, the "unobservable" quantities are parameters that parametrize a known family of probability distributions according to which the data are distributed. In other words, a sufficient statistic T(X) for a parameter θ is a statistic such that the conditional probability of the data X , given T ( X ), does not ...

  3. Rider optimization algorithm - Wikipedia

    en.wikipedia.org/wiki/Rider_optimization_algorithm

    ROA relies on the groups of rider that struggle to reach the target. ROA employs rider groups that take a trip to reach common target in order to become winner. In ROA, the count of groups is four wherein equal riders are placed. The four groups adapted in ROA are attacker, overtaker, follower, and bypass rider.

  4. Optimal stopping - Wikipedia

    en.wikipedia.org/wiki/Optimal_stopping

    A key example of an optimal stopping problem is the secretary problem. Optimal stopping problems can often be written in the form of a Bellman equation , and are therefore often solved using dynamic programming .

    en.wikipedia.org/wiki/Response_amplitude_operator

    Different modelling and design criteria will affect the nature of the 'ideal' RAO curves (as plotted graphically) being sought for a particular ship: for example, an ocean cruise liner will have a considerable emphasis placed upon minimizing accelerations to ensure the comfort of the passengers, while the stability concerns for a naval warship will be concentrated upon making the ship an ...

    Investors use the return on assets ratio formula to evaluate a company. The greater a return, the higher valuation investors are likely to provide.

  8. Weak formulation - Wikipedia

    en.wikipedia.org/wiki/Weak_formulation

    In a weak formulation, equations or conditions are no longer required to hold absolutely (and this is not even well defined) and has instead weak solutions only with respect to certain "test vectors" or "test functions". In a strong formulation, the solution space is constructed such that these equations or conditions are already fulfilled.

  9. List of mathematical examples - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_examples

    This page will attempt to list examples in mathematics. To qualify for inclusion, an article should be about a mathematical object with a fair amount of concreteness. Usually a definition of an abstract concept, a theorem, or a proof would not be an "example" as the term should be understood here (an elegant proof of an isolated but particularly striking fact, as opposed to a proof of a ...
