  2. Vector autoregression - Wikipedia

    en.wikipedia.org/wiki/Vector_autoregression

    A VAR with p lags can always be equivalently rewritten as a VAR with only one lag by appropriately redefining the dependent variable. The transformation amounts to stacking the lags of the VAR(p) variable in the new VAR(1) dependent variable and appending identities to complete the precise number of equations. For example, the VAR(2) model

  3. Impulse response - Wikipedia

    en.wikipedia.org/wiki/Impulse_response

    More generally, an impulse response is the reaction of any dynamic system in response to some external change. In both cases, the impulse response describes the reaction of the system as a function of time (or possibly as a function of some other independent variable that parameterizes the dynamic behavior of the system).

  4. Conditioned avoidance response test - Wikipedia

    The test can detect antipsychotic-like activity both in the case of dopamine D 2 receptor antagonists and in the case of drugs lacking D 2 receptor antagonism. [1] [2] [6] The occupancy of the D 2 receptor by antagonists of this receptor required to inhibit the CAR is around 65 to 80%, which is similar to the occupancy at which therapeutic antipsychotic effects occur in humans with these drugs.

    Each equation i has a single response variable y ir, and a k i-dimensional vector of regressors x ir. If we stack observations corresponding to the i-th equation into R-dimensional vectors and matrices, then the model can be written in vector form as = +, =, …,,

    Our test dog is very good-natured and puts up with a lot, but she would not allow for the full swabbing time with any of the kits. This is a common experience, so doing some prep work before the ...

    en.wikipedia.org/wiki/Canny_edge_detector

    The result of the traditional detection cannot reach a satisfactory high accuracy of a single response for each edge - multi-point responses will appear. In order to address these defects, an improvement to the canny edge algorithm is presented in the following paragraphs.

  9. Reverse correlation technique - Wikipedia

    en.wikipedia.org/wiki/Reverse_correlation_technique

    The reverse correlation technique is a data driven study method used primarily in psychological and neurophysiological research. [1] This method earned its name from its origins in neurophysiology, where cross-correlations between white noise stimuli and sparsely occurring neuronal spikes could be computed quicker when only computing it for segments preceding the spikes.
