Look at the square value of R and the value of F in the process result:
The fitted model can explain the percentage of the change of the dependent variable, for example, R square =.81, which means that the fitted equation can explain 81% of the change of the dependent variable and 19% cannot. For example, the correlation coefficient r=.66 and the determining coefficient R^2=.4356 between the IQ score of a student on an intelligence scale and his academic performance.
if the r square is 1
, the fund is completely related to the performance evaluation benchmark. R squared is , which means that the two are not related. The lower the R square, the lower the reliability of β coefficient as an index of fund volatility. The closer the R square is to 1, the more the β coefficient can reflect the volatility of the fund. In Morningstar's fund evaluation system, both β coefficient and R square are listed.
