Fuel Consumption in the study is used as an indicator variable for growth of traffic. Its used as the dependent variable in this analysis with the predictor variables in place being
Vehicle Growth Registration
County GCP
Nationals GDP
Nationals GDP per Capita
The distribution of fuel consumption can be checked using a histogram as follows.
MLR involves several predictors unlike SLR, the model equation at the end will resemble:
\(FuelCons = Intercept + \beta_0*VegicleReg + \beta_0 *GCPNairobi + \beta_2 * PopNairobi +\beta_3*GDPKenya + \beta_4*GDPperCapita\)
The equation involves 5 predictors against one response variable Fuel Consumption in KES. To optimize model performance insignificant variables would be dropped using step-wise regression method.
