more than 20,000 observations, which were all drawn from the market on March 21st 2006.
The following is the descriptive statistics of the data:
With all the variables, we have a regression formula:
Testing the existence of Multicollinearity, the matrix of Pearson correlation is shown in the following:
From the matrix above, we can see that all of the p-values are less than 0.05, which means at the 5% significance level, we reject the null hypothesis that the independent variables have no relationship with each other.
