  2. Delta ratio - Wikipedia

    en.wikipedia.org/wiki/Delta_Ratio

    Result 1: if there is a normal anion gap acidosis, the (AG – 12) part of the equation will be close to zero, the delta ratio will be close to zero and there is no mixed acid–base disorder. Your calculations can stop here. A normal anion gap acidosis (NAGMA) has more to do with a change in [Cl −] or [HCO − 3] concentrations.

  3. Delta method - Wikipedia

    en.wikipedia.org/wiki/Delta_method

    In statistics, the delta method is a method of deriving the asymptotic distribution of a random variable. It is applicable when the random variable being considered can be defined as a differentiable function of a random variable which is asymptotically Gaussian .

  4. Degrees of freedom (statistics) - Wikipedia

    en.wikipedia.org/.../Degrees_of_freedom_(statistics)

    In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary. [1] Estimates of statistical parameters can be based upon different amounts of information or data. The number of independent pieces of information that go into the estimate of a parameter is called the degrees ...

  5. Dirichlet distribution - Wikipedia

    en.wikipedia.org/wiki/Dirichlet_distribution

    In probability and statistics, the Dirichlet distribution (after Peter Gustav Lejeune Dirichlet), often denoted ⁡ (), is a family of continuous multivariate probability distributions parameterized by a vector of positive reals.

  6. Percolation critical exponents - Wikipedia

    en.wikipedia.org/wiki/Percolation_critical_exponents

    The gap exponent Δ is defined as Δ = 1/(β+γ) = 1/σ and represents the "gap" in critical exponent values from one moment to the next + for >. The conductivity exponent t = ν t ′ {\displaystyle t=\nu t'} describes how the electrical conductivity C {\displaystyle C} goes to zero in a conductor-insulator mixture, C ∼ ( p − p c ) t ...

  7. Relative change - Wikipedia

    en.wikipedia.org/wiki/Relative_change

    A percentage change is a way to express a change in a variable. It represents the relative change between the old value and the new one. [6]For example, if a house is worth $100,000 today and the year after its value goes up to $110,000, the percentage change of its value can be expressed as = = %.

    This article needs attention from an expert in statistics. The specific problem is: completion to reasonable standard for probability distributions. WikiProject Statistics may be able to help recruit an expert.

  9. Exponential distribution - Wikipedia

    en.wikipedia.org/wiki/Exponential_distribution

    In probability theory and statistics, the exponential distribution or negative exponential distribution is the probability distribution of the distance between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate; the distance parameter could be any meaningful mono-dimensional measure of the process, such as time ...
