  • Autocorrelation And Regression Analysis

    Autocorrelation is not expected to be an issue with the model, given that the it is not using time series data, and it can therefore be assumed that there is no autocorrelation present in the model. To make sure that there is no perfect collinearity present in the model, it is recommended to run a collinearity test of the model (see: Exhibit 1.1). If a variable generate a VIF (Variance Inflation Factors) value above 10.0, the model might have a collinearity problem and attempts to correct the model should be made. However, the test did not generate any VIF values above 10.0 for any of the variables, thus not suggesting any problems and also implying that the model shows no perfect collinearity i.e. not violating the assumption. Moreover, the model should be tested for specification error or bias by making sure that the omitted variables bare no significance and that irrelevant variables are not featured in the model, in order to keep bias away from the coefficients and to ensure that forecasts are reliable.
