It is said that it is performed to check whether “X causes Y”, or to put it differently, whether X contains any predictive information with regards to Y and it mainly builds two regression models (one nested to other). WebProposed by Clive Granger in 1969 [1], Granger causality analysis (GCA) has been widely applied to analyze the relationships between time series. Briefly, a time series X is said to Granger-cause time series Y if the values of X provide statistically significant information about future values of Y.
