  4. Vector flow - Wikipedia

    en.wikipedia.org/wiki/Vector_flow

    Here D ⊆ R × M is the flow domain. For each p ∈ M the map D p → M is the unique maximal integral curve of V starting at p. A global flow is one whose flow domain is all of R × M. Global flows define smooth actions of R on M. A vector field is complete if it generates a global flow. Every smooth vector field on a compact manifold without ...

  5. Error correction model - Wikipedia

    en.wikipedia.org/wiki/Error_correction_model

    Forecasts from such a model will still reflect cycles and seasonality that are present in the data. However, any information about long-run adjustments that the data in levels may contain is omitted and longer term forecasts will be unreliable. This led Sargan (1964) to develop the ECM methodology, which retains the level information. [4] [5]

    In the panel data fixed effects estimator dummies are created for each of the units in cross-sectional data (e.g. firms or countries) or periods in a pooled time-series. However in such regressions either the constant term has to be removed, or one of the dummies removed making this the base category against which the others are assessed, for ...

  9. Concept learning - Wikipedia

    en.wikipedia.org/wiki/Concept_learning

    One model that incorporates the Bayesian theory of concept learning is the ACT-R model, developed by John R. Anderson. [citation needed] The ACT-R model is a programming language that defines the basic cognitive and perceptual operations that enable the human mind by producing a step-by-step simulation of human behavior. This theory exploits ...
