While the output automatically gives the F statistic on all the independent variables, I would like the F statistic on a subset of independent variables that I specify. An example would be:</P><P></P><P>dependent = independent 1 + independent 2 +&nbsp; independent 3 + independent 4 + independent 5</P><P></P><P>I'm interested in the F statistic on the variables independent 1 - 3. Any ideas how to do this?</P><P></P><P>Thanks.</P></BODY></HTML> Sat, 20 Aug 2011 22:14:44 GMT https://communities.sas.com/t5/Statistical-Procedures/F-statistic-on-part-of-the-independent-variables/m-p/51514#M2276 JOLSAS 2011-08-20T22:14:44Z F statistic on part of the independent variables https://communities.sas.com/t5/Statistical-Procedures/F-statistic-on-part-of-the-independent-variables/m-p/51515#M2277 <HTML><HEAD></HEAD><BODY><P>Couldn't you just run the regression on those variables?</P></BODY></HTML> Sun, 21 Aug 2011 00:24:41 GMT https://communities.sas.com/t5/Statistical-Procedures/F-statistic-on-part-of-the-independent-variables/m-p/51515#M2277 art297 2011-08-21T00:24:41Z F statistic on part of the independent variables https://communities.sas.com/t5/Statistical-Procedures/F-statistic-on-part-of-the-independent-variables/m-p/51516#M2278 <HTML><HEAD></HEAD><BODY><P> No, that wouldn't be what is required. As a matter of fact, in later regressions, I would need to get the F statistics on several subsets of variables. I need to include those always.</P></BODY></HTML> Sun, 21 Aug 2011 00:35:30 GMT https://communities.sas.com/t5/Statistical-Procedures/F-statistic-on-part-of-the-independent-variables/m-p/51516#M2278 JOLSAS 2011-08-21T00:35:30Z F statistic on part of the independent variables https://communities.sas.com/t5/Statistical-Procedures/F-statistic-on-part-of-the-independent-variables/m-p/51517#M2279 <HTML><HEAD></HEAD><BODY><P> I don't know if SAS contains such an option enabling me to do so. Anyways, I went to find the statistical formula for calculating the F statistic and calculated all the components of F and got a number in the end. Hopefully this is what I want.</P></BODY></HTML> Sun, 21 Aug 2011 02:39:25 GMT https://communities.sas.com/t5/Statistical-Procedures/F-statistic-on-part-of-the-independent-variables/m-p/51517#M2279 JOLSAS 2011-08-21T02:39:25Z F statistic on part of the independent variables https://communities.sas.com/t5/Statistical-Procedures/F-statistic-on-part-of-the-independent-variables/m-p/51518#M2280 <HTML><HEAD></HEAD><BODY><P>Have you checked the output using a contrast statement?</P></BODY></HTML> Mon, 22 Aug 2011 16:11:16 GMT https://communities.sas.com/t5/Statistical-Procedures/F-statistic-on-part-of-the-independent-variables/m-p/51518#M2280 Reeza 2011-08-22T16:11:16Z
