Dear Jinsong,
I assume from your question that X3 and X4 are also available as

the model as tsls(Y ~ X1 + X2 + X3 + X4, instruments = ~ A + B + X3 + X4,

You need to be _extremely_ careful when assigning levels of factors. Look at
this example:
R> x1 = factor(c("a", "b", "c"))
R> x2 = factor(c("a", "c", "c"))
R> x3 = x2
R> levels(x3) <- levels(x1)

Dear Ola,
I cannot say anything about Windows 7, as we do not have any Win7
machines here in our institute and I even do not know someone who have
Win7 on a private machine. I will try to find a machine with this OS and
test it.
Anybody having experiences with Win7 yet?

Dear R users.
Does anyone know a package where the non-parametric rank test from Corrado (A
nonparametric test for abnormal security-price performance in event studies,
Charles J. Corrado, 1989, Journal of Financial Economics) for event studies is
implemented?
Sincerely
Andreas.

of anova, a linear regression to determine the split (minimize some criterion
like sum of rss left and right of the split). The regression (lm) should simply

link between title, keyword and frequency of the keywords in order to
have a 3 d plot?
