How to interpret F- and p-value in ANOVA?
I found that I can use ANOVA also for ONE Model, doing something like:
> anova(lm(a~b))
Analysis of Variance Table
Response: a
Df Sum Sq Mean Sq F value Pr(>F)
b 1 0.002679 0.0026791 11.191 0.0009001 ***
Residuals 398 0.095282 0.0002394
---
Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1
I know that ANOVA check the means BUT what test is that if I use only ONE model? If the p.value is above 0.05 it means that the regression fit good?
