Re: [R] anova.lm F test confusion

What if the model isn't nested, i.e. I want to test y=x+w vs y=x+z+v. Is there a valid test/method to compare these (other than comparing R squared values)? They are both multiple regression models. -- View this message in context: http://r.789695.n4.nabble.com/anova-lm-F-test-confusion-tp44

[R] anova.lm F test confusion

I am using anova.lm to compare 3 linear models. Model 1 has 1 variable, model 2 has 2 variables and model 3 has 3 variables. All models are fitted to the same data set. anova.lm(model1,model2) gives me: Res.DfRSS Df Sum of Sq FPr(>F) 1135 245.38

Re: [R] anova.lm F test confusion

Sorry...typo ***<-- I don't get why the MSE of model 3 is being included if we're comparing Model 2 to Model 1 -- View this message in context: http://r.789695.n4.nabble.com/anova-lm-F-test-confusion-tp4490211p4490220.html Sent from the R help mailing list archive at Nabble.com. __
