Application of Correlation Coefficient and Biased Correlation Coefficient in Related Analysis

In the related analysis, the correlation coefficient is generally used to analyze and determine the linear's related degrees of variables. Because it is affected by other factors, what the simple correlation coefficient reflects is not the essence of relations. In order to reflect exactly the internal relations between the two economic variables, it needs calculating the biased correlation coefficient. By comparison with biased correlation coefficient and correlation coefficient, it will be more real and reliable to determine the internal linear relations between the two variables.
