There are no other variable types in SPSS than string and numeric. Take R and raise it to the second power. using a Time Ordered Restricted Vector Autoregressive Model Elsa Siggiridou and Dimitris Kugiumtzis Abstract—Granger causality has been used for the investigation of the inter-dependence structure of the underlying systems of multi-variate time series. r squared, represents the proportion of variance in one variable that is explained for by another variable.
