Chapter I Introduction Regression analysis is a statistical tool for the investigation of relationships between variables. The investigator seeks to ascertain the causal effect of one variable upon another—the effect of a price increase upon demand‚ for example‚ or the effect of changes in the money supply upon the inflation rate. To explore such issues‚ the investigator assembles data on the underlying variables of interest and employs regression to estimate the quantitative effect of the causal
