  2. Allele frequency - Wikipedia

    en.wikipedia.org/wiki/Allele_frequency

    Allele frequency, or gene frequency, is the relative frequency of an allele (variant of a gene) at a particular locus in a population, expressed as a fraction or percentage. [1] Specifically, it is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.

  3. Frequency (statistics) - Wikipedia

    en.wikipedia.org/wiki/Frequency_(statistics)

    Under the frequency interpretation of probability, it is assumed that as the length of a series of trials increases without bound, the fraction of experiments in which a given event occurs will approach a fixed value, known as the limiting relative frequency. [7] [8] This interpretation is often contrasted with Bayesian probability.

  4. Empirical probability - Wikipedia

    en.wikipedia.org/wiki/Empirical_probability

    In probability theory and statistics, the empirical probability, relative frequency, or experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, [1] i.e. by means not of a theoretical sample space but of an actual experiment.

  5. Law of large numbers - Wikipedia

    en.wikipedia.org/wiki/Law_of_large_numbers

    This theorem makes rigorous the intuitive notion of probability as the expected long-run relative frequency of an event's occurrence. It is a special case of any of several more general laws of large numbers in probability theory. Chebyshev's inequality. Let X be a random variable with finite expected value μ and finite non-zero variance σ 2.

  6. Selection coefficient - Wikipedia

    en.wikipedia.org/wiki/Selection_coefficient

    The fitness of a genotype is a measure of its reproductive success, often expressed as a fraction of the maximum reproductive success in the population. The formula to calculate the selection coefficient s {\displaystyle s} for a genotype is: s = 1 − W {\displaystyle s=1-W} , where W {\displaystyle W} is the relative fitness of the genotype ...

  7. Rate (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Rate_(mathematics)

    In mathematics, a rate is the quotient of two quantities, often represented as a fraction. [1] If the divisor (or fraction denominator) in the rate is equal to one expressed as a single unit, and if it is assumed that this quantity can be changed systematically (i.e., is an independent variable), then the dividend (the fraction numerator) of the rate expresses the corresponding rate of change ...

  9. Fresnel equations - Wikipedia

    en.wikipedia.org/wiki/Fresnel_equations

    These formulas [14] [15] [16] are known respectively as Fresnel's sine law and Fresnel's tangent law. [17] Although at normal incidence these expressions reduce to 0/0, one can see that they yield the correct results in the limit as θ i → 0 .
