81Discrete Fourier transform — Fourier transforms Continuous Fourier transform Fourier series Discrete Fourier transform Discrete time Fourier transform Related transforms In mathematics, the discrete Fourier transform (DFT) is a specific kind of discrete transform, used in… …
82Estimator — In statistics, an estimator is a function of the observable sample data that is used to estimate an unknown population parameter (which is called the estimand ); an estimate is the result from the actual application of the function to a… …
83Online model — An online model is a mathematical model which tracks and mirrors a plant or process in real time, and which is implemented with some form of automatic adaptivity to compensate for model degredation over time. Contents 1 Relationship to other… …
84Consistent estimator — {T1, T2, T3, …} is a sequence of estimators for parameter θ0, the true value of which is 4. This sequence is consistent: the estimators are getting more and more concentrated near the true value θ0; at the same time, these estimators are biased.… …
85Cumulative frequency analysis — is the applcation of estimation theory to exceedance probability (or equivalently to its complement). The complement, the non exceedance probability concerns the frequency of occurrence of values of a phenomenon staying below a reference value.… …
86Kaplan–Meier estimator — The Kaplan–Meier estimator,[1][2] also known as the product limit estimator, is an estimator for estimating the survival function from life time data. In medical research, it is often used to measure the fraction of patients living for a certain… …
87Checking whether a coin is fair — In statistics, the question of checking whether a coin is fair is one whose importance lies, firstly, in providing a simple problem on which to illustrate basic ideas of statistical inference and, secondly, in providing a simple problem that can… …
88Tikhonov regularization — Tikhonov regularization, named for Andrey Tikhonov, is the most commonly used method of regularization of ill posed problems. In statistics, the method is known as ridge regression, and, with multiple independent discoveries, it is also variously …
89List of theories — This is a list of topics commonly referred to as theory .This is not a list of theorems or theories (e.g., Theory of relativity, String theory) but branches of knowledge with theory in their name.*Atomic theory *Automata theory *Axiomatic set… …
90Цифровая обработка сигналов — (ЦОС, DSP  англ. digital signal processing)  преобразование сигналов, представленных в цифровой форме. Любой непрерывный (аналоговый) сигнал может быть подвергнут дискретизации по времени и квантованию по уровню (оцифровке), то… …
