What's univariate time series data? Is that like plotting time on x =
axis and approval on y? or is it just like a plot of a variable of our =
choice on x and approval on y?

In terms of lagging variables in lm(), is it necessary to create a new column
of variables in the dataframe corresponding to Y_t-1 etc. (this is the way we
did it in 1000), or is there a convenient way that R can handle this?
Thanks,
Phillip.

As I mentioned in class, you are invited to an end-of-semester party at
our house on Saturday May 17th at 11am for lunch, etc. Please feel free
to bring someone along (and kids are invited as well). Ella Michelle (7),
Elizabeth (>7), and Blizzard and Snowflake (0.5 and 1.7 dog years,
respectively) will be there too. We're at 9 Beecher Road, in Brookline.
Its about 5 miles from HU, and easy to get to by Bus, T, or car.
Directions are at http://gking.harvard.edu/directions
I'd appreciate if you'd RSVP soon, by responding to this email, so I
can get a count for food. Let me know whether you can make it and if
you'll be bringing someone. I hope you can make it.

Hi,
For the formula on past shocks (slide 78 on smodels.pdf), should the
second-to-last formula be:
\mu_i = x_i \beta - (y_1 - \mu_1)(-\phi)^{i - 1} <- (was just i)
- \sum_{j-1}^{i-2} <- (was i-1)
...
I've checked this out with i=4 and it seems to be correct.
Charles
You might want to replace the last line of ternary() with
points((X[,2] - X[,3])*s3, X[,1], pch=pch, ...)
This way, your input for "pch" won't get ignored!
Kosuke
Hi
I would like to number each equation (such as the one we get with cases) and
have a left curly brace to embrace all the equations.
for example (Latex, Leslie Lamport page 49)
x={ y if y > 0
{ z+y otherwise
\[ x = \left{ \begin{array}{ll}
y & \mbox{ if $y > 0 $ \\
z+y & \mbox{otherwise}
\end{array}
\right. \]
what I want is to number each line as follow
x={ y if y > 0 (1)
{ z+y otherwise (2)
Any suggestions?
Thanks
Vick

I am having a strange VNC problem. I can't log on to VNC (ok, so I need
to vncfinger, make sure I have a session, and vncserver to get a new one).
However, at every prompt (ice1,ice2,fas,...) vncfinger begets "Command not
found".
When Colin logs on to the same server I try (whether he has a session
there or not), he can vncfinger/vncserver with no problem.
Help!

In the lecture notes, when gary uses capital F in the log-likelihood of =
the ordinal probit model, he means the CDF of the standard normal and =

In class, Gary mentioned the neccessity of having a control group in
experiements, in order to establish causal relationship between the
explanatory variable and the dependent variable. In regression though, is
this the same as having variation in the explanatory variable? Or is there
difference between the two and, if so, can someone kindly explain it to me?
