Determining the key drivers of Sydneys price [pic 1]Executive SummaryThis report will contain an analysis of the effect that several independent variables have on an Index that measures the value of Sydneys Property Prices over 1994-2014. In order to find these variables and understand their importance, we utilised an OLS regression model to optimise and then signify the level of variance explained by each variable. Overall, we were able to successfully find several variables which provided a level of understanding for our dependent variable and the methodology and actual empirical results will be demonstrated and evaluated through the report.  Contents1        Executive Summary        2        Introduction        3        Related literature        4        Data and methodology        4.1        Data        4.2        Methodology        4.3        Multicollinearity Test        5        Empirical results        5.1        Table and analysis        5.2        Notes on sources of error        6        Conclusion        7        Appendix        7.1        Reference        7.2        Further graphs        7.3        Matlab Code        IntroductionThe rise in Sydneys house prices over the past 20 years has been unprecedented, growing 355% since 1994 or at CAGR of 13.51%.
