WebThis estimation method gives rise to residual based tests for cointegration. It was shown by Phillips and Hansen [42] that a modification of the regression estimator, involving a correction using the long-run variance of the process ut,would give useful methods for inference for coefficients of cointegration relations; see also Phillips [41]. WebCointegration has become an important property in contemporary time series analysis. Time series often have trends—either deterministic or stochastic . In an influential paper, …

V ECTOR auto-regressive (VAR) integrated model comprises multiple time series and is quite a useful tool for forecasting. It can be considered an extension of the auto-regressive (AR part of ARIMA) model. VAR model involves multiple independent variables and therefore has more than one equations. spider man pushing people off buildings
