Correlation Coefficient Factor

[Daniel Fan]

Hi Alex:

I am reading 肯恩費雪 的 "投資的三個問題" - It mentions that sometimes we are too focus to try to find out the correlation between one indicator to the result of price up or down.  We should take enough data to plug in the "Correlation Coefficient Factor" to evaluate these relationship is true or not. He provides the formula to allow us to figure out ourselves.  I think it is interesting for our finding Gap's impact on stock price project.  I have made a copy of these few pages.  If you need the book, let me know.

Best Regards,

Daniel
