Frequency estimation — This article is about the technique in signal processing. The term frequency estimation can also refer to probability estimation. Frequency estimation is the process of estimating the complex frequency components of a signal in the presence of… … Wikipedia
Frequency distribution — In statistics, a frequency distribution is an arrangement of the values that one or more variables take in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and… … Wikipedia
Method of moments (statistics) — See method of moments (probability theory) for an account of a technique for proving convergence in distribution. In statistics, the method of moments is a method of estimation of population parameters such as mean, variance, median, etc. (which… … Wikipedia
Frequency (statistics) — In statistics the frequency of an event i is the number ni of times the event occurred in the experiment or the study. These frequencies are often graphically represented in histograms. We speak of absolute frequencies, when the counts ni… … Wikipedia
Frequency probability — Statistical probability redirects here. For the episode of Star Trek: Deep Space Nine, see Statistical Probabilities. John Venn Frequency probability is the interpretation of probability that defines an event s probability as the limit of its… … Wikipedia
Pisarenko harmonic decomposition — Pisarenko harmonic decomposition, also referred to as Pisarenko s method, is a method of frequency estimation [Hayes, Monson H., Statistical Digital Signal Processing and Modeling , John Wiley Sons, Inc., 1996. ISBN 0 471 59431 8.] . This method… … Wikipedia
Reassignment method — The method of reassignment is a technique forsharpening a time frequency representation by mappingthe data to time frequency coordinates that are nearer tothe true region of support of theanalyzed signal. The method has been… … Wikipedia

Multigrid method — Multigrid (MG) methods in numerical analysis are a group of algorithms for solving differential equations using a hierarchy of discretizations. They are an example of a class of techniques called multiresolution methods, very useful in (but not… … Wikipedia
Spectral method — Spectral methods are a class of techniques used in applied mathematics and scientific computing to numerically solve certain Dynamical Systems, often involving the use of the Fast Fourier Transform. Where applicable, spectral methods have… … Wikipedia
Prony's method — Prony analysis (Prony s method) was developed by Gaspard Riche de Prony in 1795. However, practical use of the method awaited the digital computer [1] . Similar to the Fourier transform, Prony s method extracts valuable information from a… … Wikipedia
