[R] table of variance analysis

[Lecca Paola]

Hello everybody !

I want to evaluate the goodness of the fit of a trend surface. I use the
Least square methods and the function surf.ls. The I write

tma3.sur3 <- surf.ls(3, x, y, z)
summary(tma3.sur3)

Now the question: is the Pr(>F) the probability to obtain a value of
F equal or greater than the obtained one ? Is the confidence level 0.05 ?

Thanks a lot for any help.
Paola.
