Vector autoregression — (VAR) is an econometric model used to capture the evolution and the interdependencies between multiple time series, generalizing the univariate AR models. All the variables in a VAR are treated symmetrically by including for each variable an… … Wikipedia
Vector quantization — is a classical quantization technique from signal processing which allows the modeling of probability density functions by the distribution of prototype vectors. It was originally used for data compression. It works by dividing a large set of… … Wikipedia
Vector control (motor) — Vector control (also called Field Oriented Control, FOC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three phase AC electric motors by controlling the current fed to the machine.MethodThe… … Wikipedia
Errors-in-variables models — In statistics and econometrics, errors in variables models or measurement errors models are regression models that account for measurement errors in the independent variables. In contrast, standard regression models assume that those regressors… … Wikipedia
Errors and residuals in statistics — For other senses of the word residual , see Residual. In statistics and optimization, statistical errors and residuals are two closely related and easily confused measures of the deviation of a sample from its theoretical value . The error of a… … Wikipedia
Vector (STL) — Vectors (or std::vector) are a C++ implementation of the dynamic array data structure. Their interface emulates the behavior of a C array (i.e., capable of fast random access) but with the additional ability to automatically resize itself when… … Wikipedia
Vector Field Histogram — In robotics, Vector Field Histogram (VFH) is a real time motion planning algorithm proposed by Johann Borenstein and Yoram Koren in 1991.cite journal author = Borenstein, J. coauthors = Koren, Y. year = 1991 title = The vector field histogram… … Wikipedia
Vector signal analyzer — The vector signal analyzer (VSA) is a powerful tool that can perform many of the same measurement and characterization tasks that the spectrum analyzer (SA) can, but it can also perform many more useful digital demodulation functions. The VSA is… … Wikipedia

Ad-hoc On-demand Distance Vector — Der Ad hoc On demand Distance Vector Routingalgorithmus (AODV) ist ein Algorithmus zum Weiterleiten von Daten durch ein mobiles Ad hoc Netz. Das Protokoll gehört zu den topologiebasierten, reaktiven Routingverfahren, d. h. Routen zu… … Deutsch Wikipedia
Heteroscedasticity-consistent standard errors — In statistics, a frequent assumption in linear regression is that the disturbances u i have the same variance. When this is not the case, we get heteroskedasticity in the estimated residuals scriptstylewidehat{u i} . Heteroskedasticity consistent … Wikipedia
