Glossary of common statistical, machine learning, data science terms used commonly in industry. An autoregressive model is when a value from a time series is regressed on previous values from that This model is a second-order autoregression, written as GitHub is where people build software. This section includes a list of references, related reading or external links, but its sources remain unclear because it lacks inline citations. Autoregressive models and processes are stochastic calculations in which future values are estimated based on a weighted sum of past values. Autoregression is a time series model that uses observations from previous time steps as input to a regression equation to predict the value at the next time step. The main features of this release are several new time series models based on the statespace framework, multiple imputation using MICE as well as many other enhancements.
