ANOVA and F-statistic

  • Follow


Hi there,

When using the anova1() and then looking at the F-statistic, I don't get the same value when determining it separately in workspace. I'm using this code in the test

X = [-1.4969 1.7449 2.7270; 1.4413 2.1644 4.5763;  -0.3981 2.7477 2.5191];
anova1(X)

providing an F=7.41. Then trying with this code

F = finv(1-0.05,2,6);

provides F=5.14. The degrees of freedom are of course determined on the basis of X, but the significance level does not seem to fit the stadard 0.05 or 0.01. It F in the ANOVA table not the same F-statistic as usual?

Thanks

I mixed up the F statistic in the ANOVA table with the comparation level for accepting the H0 hypothesis, which are not equal.
