lm diagnostics and qr (fwd)
...( the
median of the F distribution with paramaters p=# of variables in design,
number of obs.-p) but does not give same answer.
Lastly, the qr function is supposed to take the LAPACK package in its
default but it seems to default LINPACK. The following appears only when
qr(x, LAPACK=T)
attr(,"useLAPACK")
[1] TRUE
Thank you for all your help,
