F (F-test): ForF statisticprovides the overall importance of the regression model for the null hypothesis. If you divide theMSof regression by theMSof Residual, you’ll get theF-test. Significance F: Significance Fis a crucial term to find the output of your model whether it is statisticall...

In the regression output above, we can see that for every one-point change in Visa, there is a corresponding 1.36-point change in the S&P 500. We can also see that the p-value is very small (0.000036), which also corresponds to a very large T-test. This indicates that this finding ...

Ftest number for the F test of the statistical significance of the regression model as a whole (you must find the Fcritical number from an F table, or use Excel to calculate Fcritical on the side). The "Significance F" number is the p-value for the F-test. In this example, the p...
Stata好像在台灣用的人不多,網路上看到的中文資料似乎很少,但它真的是個好物啊!如果用SPSS跑了regression之後,還要花很多時間畫成表格,但這點在stata只要下幾個指令就好了,然後就可以輸出成word檔(rtf格式)和excel檔,避免你打錯。 網址:http://repec.org/bocode/e/e
