  2. Likelihood function - Wikipedia

    en.wikipedia.org/wiki/Likelihood_function

    [16] [21] In a slightly different formulation suited to the use of log-likelihoods (see Wilks' theorem), the test statistic is twice the difference in log-likelihoods and the probability distribution of the test statistic is approximately a chi-squared distribution with degrees-of-freedom (df) equal to the difference in df's between the two ...

  3. Binomial distribution - Wikipedia

    en.wikipedia.org/wiki/Binomial_distribution

    In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p).

  4. Bayes' theorem - Wikipedia

    en.wikipedia.org/wiki/Bayes'_theorem

    Beyond, for example, assigning binary truth values, here one assigns probability values to statements. The assertion of B → A {\displaystyle B\to A} is captured by the assertion P ( A | B ) = 1 {\displaystyle P(A\vert B)=1} , i.e. that the conditional probability take the extremal probability value 1 {\displaystyle 1} .

  5. Stochastic differential equation - Wikipedia

    en.wikipedia.org/wiki/Stochastic_differential...

    A stochastic differential equation (SDE) is a differential equation in which one or more of the terms is a stochastic process, [1] resulting in a solution which is also a stochastic process. SDEs have many applications throughout pure mathematics and are used to model various behaviours of stochastic models such as stock prices , [ 2 ] random ...

  6. Maximum likelihood estimation - Wikipedia

    en.wikipedia.org/wiki/Maximum_likelihood_estimation

    The maximum likelihood estimator selects the parameter value which gives the observed data the largest possible probability (or probability density, in the continuous case). If the parameter consists of a number of components, then we define their separate maximum likelihood estimators, as the corresponding component of the MLE of the complete ...

  7. Girsanov theorem - Wikipedia

    en.wikipedia.org/wiki/Girsanov_theorem

    We assume that this equation has a unique strong solution on [,]. In this case Girsanov's theorem may be used to compute functionals of X t {\displaystyle X_{t}} directly in terms a related functional for Brownian motion.

  8. Wilks' theorem - Wikipedia

    en.wikipedia.org/wiki/Wilks'_theorem

    For example: If the null model has 1 parameter and a log-likelihood of −8024 and the alternative model has 3 parameters and a log-likelihood of −8012, then the probability of this difference is that of chi-squared value of (()) = with = degrees of freedom, and is equal to .

  9. Probability theory - Wikipedia

    en.wikipedia.org/wiki/Probability_theory

    That is, the probability function f(x) lies between zero and one for every value of x in the sample space Ω, and the sum of f(x) over all values x in the sample space Ω is equal to 1. An event is defined as any subset of the sample space . The probability of the event is defined as
