  2. Logistic map - Wikipedia

    en.wikipedia.org/wiki/Logistic_map

    In this case, the variable x of the logistic map is the number of individuals of an organism divided by the maximum population size, so the possible values of x are limited to 0 ≤ x ≤ 1. For this reason, the behavior of the logistic map is often discussed by limiting the range of the variable to the interval [0, 1]. [Hirsch,Smale & Devaney 1]

  3. Tent map - Wikipedia

    en.wikipedia.org/wiki/Tent_map

    Higher density indicates increased probability of the x variable acquiring that value for the given value of the μ parameter. The tent map with parameter μ = 2 and the logistic map with parameter r = 4 are topologically conjugate, [1] and thus the behaviours of the two maps are in this sense identical under iteration.

  4. Exchangeable random variables - Wikipedia

    en.wikipedia.org/wiki/Exchangeable_random_variables

    Partition the sequence into non-overlapping pairs: if the two elements of the pair are equal (00 or 11), discard it; if the two elements of the pair are unequal (01 or 10), keep the first. This yields a sequence of Bernoulli trials with p = 1 / 2 , {\displaystyle p=1/2,} as, by exchangeability, the odds of a given pair being 01 or 10 are equal.

  5. Logistic regression - Wikipedia

    en.wikipedia.org/wiki/Logistic_regression

    The data points are indexed by the subscript k which runs from = to = =. The x variable is called the "explanatory variable", and the y variable is called the "categorical variable" consisting of two categories: "pass" or "fail" corresponding to the categorical values 1 and 0 respectively.

  6. Stochastic simulation - Wikipedia

    en.wikipedia.org/wiki/Stochastic_simulation

    The system usually change over time, variables of the model, then change continuously as well. Continuous simulation thereby simulates the system over time, given differential equations determining the rates of change of state variables. [16] Example of continuous system is the predator/prey model [17] or cart-pole balancing [18]

  7. Markov kernel - Wikipedia

    en.wikipedia.org/wiki/Markov_kernel

    In probability theory, a Markov kernel (also known as a stochastic kernel or probability kernel) is a map that in the general theory of Markov processes plays the role that the transition matrix does in the theory of Markov processes with a finite state space.

  8. Maximum a posteriori estimation - Wikipedia

    en.wikipedia.org/wiki/Maximum_a_posteriori...

    The MAP can be used to obtain a point estimate of an unobserved quantity on the basis of empirical data. It is closely related to the method of maximum likelihood (ML) estimation, but employs an augmented optimization objective which incorporates a prior density over the quantity one wants to estimate.

  9. Pushforward measure - Wikipedia

    en.wikipedia.org/wiki/Pushforward_measure

    If (,,) is a probability space, (,) is a measurable space, and : is a (,)-valued random variable, then the probability distribution of is the pushforward measure of by onto (,). A natural " Lebesgue measure " on the unit circle S 1 (here thought of as a subset of the complex plane C ) may be defined using a push-forward construction and ...
