The output with all three fits gives you 2 comparisons, fit1 vs. fit2 and fit2
vs. fit3.
So using an alpha of 0.05, the 0.99 p-value is comparing model 2 (fit2) and
model 3 (fit1) and testing the null that they fit equally well with the
differences being due to random chance. The p-value is

Hello,
I've got a question concerning the usage of robust standard errors in
regression using lm() and exporting the summaries to LaTeX using the
memisc-packages function mtable():
Is there any possibility to use robust errors which are obtained by
vcovHC() when generating the LateX-output
I assume you mean PDFs generated by R. This topic has been addressed
here: http://tolstoy.newcastle.edu.au/R/e2/help/07/05/17475.html
I have always just output the graphics then used an external PDF
program (like Preview on the Mac) to do changes in file type, size
reductions, etc.

I always use apsrtable in the apsrtable package, which allows you to
specify a vcov matrix using the se option. The only trick is that
you have to append it to your model object, something like this:
fit=lm(y ~ x)
fit$se=vcovHC(fit)
apsrtable(fit, se=robust)

Hello,
I want to save a pdf plot using Cairo, but the canvas of the saved file
seems too large when compared to the actual plotted area.
Is there a way to control the relation between the canvas size and the size
