Details | A regression analysis model is employed to verify the correlation between two variables; fundamentally, it is a model for analyzing the correlation in the current fiscal year or the correlation considering the time lag in a single year only. However, the impact of one variable on another will not only appear in that year but also over multiple years. We have already proposed a quantitative analysis model that considers several time lags for an explained variable. Meanwhile, it seems to be an essential issue how an explained variable in the current fiscal year is influenced by explanatory variables before the current fiscal years. Against this background, this study proposes a quantitative analysis model, in which explanatory variables have several time lags with explained variables. |
