A study on the relationship between interest rate (BLR), population and gross domestic product towards Proton car sales in Malaysia / Jamilah Hussin @ Jaafar

This research paper attempts to determine the relationship between interest rate, population and gross domestic product (GDP) towards Proton car sales. The data is collected for 8 years starting from year 1997 to 2004 in quarterly basis. The methods used are Simple Linear Regression Model and Multiple Linear Regression Model. Based on analysis from simple linear regression model, the result shows that there are significant relationships between interest rate, population and GDP with Proton car sales. The result also shows that there are positive relationships between population and GDP, meanwhile for interest rate the result shows a negative relationship between Proton car sales. Under the multiple linear regression models, the result shows that all selected variable (interest rate, population and GDP) have significant relationships with Proton car sales simultaneously. From the F-statistic, the result shows that the model reliably predicts the dependent and independent variables.
