to research possible within-variable correlation. To get a general first impression of possible correlation with the past values of the vehicle crime variables, three lags are taken indicating that we look back three months in time. The lag periods are denoted by L1 for the first lag, which looks back one month; L2, for two months back; and L3, three months back.
