Therefore, OLS is used to perform linear regression analysis on the logarithmic series of the two prices, and then the equation residuals are obtained to check whether they are stable
Therefore, olS is used to perform linear regression analysis on the logaritht sequence of the two prices, and then obtain the equation residuals to test whether it is stable.
