  2. Binomial coefficient - Wikipedia

    en.wikipedia.org/wiki/Binomial_coefficient

    This number can be seen as equal to the one of the first definition, independently of any of the formulas below to compute it: if in each of the n factors of the power (1 + X) n one temporarily labels the term X with an index i (running from 1 to n), then each subset of k indices gives after expansion a contribution X k, and the coefficient of ...

  3. Mark and recapture - Wikipedia

    en.wikipedia.org/wiki/Mark_and_recapture

    K = Number of animals captured on the second visit k = Number of recaptured animals that were marked. A biologist wants to estimate the size of a population of turtles in a lake. She captures 10 turtles on her first visit to the lake, and marks their backs with paint. A week later she returns to the lake and captures 15 turtles.

  4. Selection coefficient - Wikipedia

    en.wikipedia.org/wiki/Selection_coefficient

    Selection coefficient, usually denoted by the letter s, is a measure used in population genetics to quantify the relative fitness of a genotype compared to other genotypes. . Selection coefficients are central to the quantitative description of evolution, since fitness differences determine the change in genotype frequencies attributable to selecti

  5. Binomial theorem - Wikipedia

    en.wikipedia.org/wiki/Binomial_theorem

    In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial.According to the theorem, the power ⁠ (+) ⁠ expands into a polynomial with terms of the form ⁠ ⁠, where the exponents ⁠ ⁠ and ⁠ ⁠ are nonnegative integers satisfying ⁠ + = ⁠ and the coefficient ⁠ ⁠ of each term is a specific positive integer ...

  6. Elimination rate constant - Wikipedia

    en.wikipedia.org/wiki/Elimination_rate_constant

    The elimination rate constant K or K e is a value used in pharmacokinetics to describe the rate at which a drug is removed from the human system. [1] It is often abbreviated K or K e. It is equivalent to the fraction of a substance that is removed per unit time measured at any particular instant and has units of T −1.

    November retail sales grew at a faster pace than Wall Street analysts had expected, reflecting continued resilience in the American consumer and indicating that the holiday shopping season in the ...

  9. Binomial distribution - Wikipedia

    en.wikipedia.org/wiki/Binomial_distribution

    This is because for k > n/2, the probability can be calculated by its complement as (,,) = (,,). Looking at the expression f(k, n, p) as a function of k, there is a k value that maximizes it. This k value can be found by calculating
