Hi everyone,
I posted some useful handouts from a probability class to my FAS space. The
documents "Distributions" and "Sums of Independent RVs" are
particularly
helpful.

New subject: [gov2001-l] Clarification on Eq. (3.4) on page 44 in our book
Hi everyone,
Am I misreading what the book says, or is the equation (3.4) on
page 44 supposed to begin with Pr(Y_i = 1) instead of Pr(Y_i = 2)?
Thank you!

New subject: [gov2001-l] Clarification on Eq. (3.5) on page 45 in our book
Hi again,
Am I missing something again, or is equation (3.5) on page 45
in the book supposed to say "for y_i = 0, 1, ..., N" instead
of "for y_i = 0, 1, ..., n"?
Thank you!

In 3.5 I think it says n instead of N because n refers to the number of obs
in a particular sample (observed realization of the random variable Y see
p.7), but in this context you could also say N since n=N.
In 3.4 I think it's a typo (seems like it should be Y_i=1).

New subject: [gov2001-l] Default round() setting
Hi all,
does anyone know how to change the default setting for the round() command? At
the moment, it is set to round to an even number, so round(0.5) goes to 0, and
round(-1.5) goes to -2. I'd like to change it such that .5 always rounds up to
the next digit.
Cheers,
Oliver

There is also trunc(). When using any of these watch out for how they deal
with negative numbers. This can be non-intuitive at first.

floor(-1.4)
[1] -2
ceiling(-1.4)

This is somewhat belated -- I forgot to add the actual link for the
probability handouts.
