21Optical coherence tomography — Intervention Optical Coherence Tomography (OCT) image of a sarcoma MeSH …
22Galton's problem — Galton’s problem, named after Sir Francis Galton, is the problem of drawing inferences from cross cultural data, due to the statistical phenomenon now called autocorrelation. The problem is now recognized as a general one that applies to all… …
23Chirp — For other uses, see Chirp (disambiguation). A chirp is a signal in which the frequency increases ( up chirp ) or decreases ( down chirp ) with time. In some sources, the term chirp is used interchangeably with sweep signal.[1] It is commonly used …
24Particle image velocimetry — (PIV) is an optical method used to measure velocities and related properties in fluids. The fluid is seeded with particles which, for the purposes of PIV, are generally assumed to faithfully follow the flow dynamics. It is the motion of these… …
25Fluctuation dissipation theorem — In statistical physics, the fluctuation dissipation theorem is a powerful tool for predicting the non equilibrium behavior of a system such as the irreversible dissipation of energy into heat from its reversible fluctuations in thermal… …
26Constant amplitude zero autocorrelation waveform — A Constant Amplitude Zero AutoCorrelation waveform (abbreviated CAZAC) is a periodic complex valued signal with modulus one and out of phase periodic (cyclic) autocorrelation equal to zero. CAZAC sequences find application in wireless… …
27Transiogram — is the accompanying spatial correlation measure of Markov chain random fields and an important part of Markov chain geostatistics. It is defined as a transition probability function over the distance lag. Simply, a transiogram refers to a… …
28Regréssion fallacieuse — Régression fallacieuse Pour les articles homonymes, voir Régression. La régression fallacieuse désigne une situation dans laquelle l utilisation de séries temporelles non stationnaires dans une régression linéaire fait apparaître des résultats… …
29Régression fallacieuse — Pour les articles homonymes, voir Régression. La régression fallacieuse désigne une situation dans laquelle l utilisation de séries temporelles non stationnaires dans une régression linéaire fait apparaître des résultats erronés, trop optimistes …
30Staionnarité d'une série temporelle — Stationnarité d une série temporelle Une des grandes questions dans l étude de séries temporelles (ou chronologiques) est de savoir si celles ci suivent un processus stationnaire. On entend par là le fait que la structure du processus sous jacent …
