R book for economists
Dear Group, I am an economics student starting with PhD work in London. As preparation I would like to get to know R a little bit better. For Stata there are tons of books, however, can you recommend a book for R? I have some substantiated econometrics knowledge, so it should be more a how-to book. Best regards Thiemo --- Thiemo Fetzer, Economist http://freigeist.devmag.net

turning comma separated string from multiple choices into flags
Hello, I use google docs' Forms to conduct surveys online. Multiple choices questions are coded as comma separated values. For example, if the question is like: 1.

The economist's term "fixed effects model" - plain lm() should work
> CAN YOU TELL ME HOW TO FIT FIXED-EFFECTS MODEL WITH R? THANK YOU! Ordinary lm() might suffice. In the code below, I try to simulate a dataset from a standard earnings regression, where log earnings is quadratic in experience, but the intercept floats by education category - you have 4 intercepts for 4 education categories. I think this works as a simple implementation of "the fixed

R vs Matlab: which is more "programmer friendly"?
...rse on numerical methods in economics. They are trying to decide which software to use for that, and I would like to advocate R. The other alternative is Matlab. I have found comparisons in terms of computational time for matrix algebra, but I don't think that is relevant: the bottleneck for economists is usually the programmer's time: if it takes a couple of hours to write something that is run only a few times, one should not care whether it runs in 2 or 2.1 minutes... I am an economist, and I have used Octave, but only until I found R. So I am not in a position to evaluate Matlab vs R. I...

End Chinese Censorship at Yahoo!
Dear Friends, I read in a September 2002 edition of the Economist Magazine that Yahoo! (www.yahoo.com) has signed an agreement with the Chinese government to censor searches on their web site for consumers in China. I am very disappointed in Yahoo! and hope you are too. To let my distaste be known, I am writing Yahoo! and closing my email accounts and un-subscribing from Yahoo!-based mailing

A query about na.omit

concerning econometrics usage of "R"
Hi, I am currently looking for a program or programmng language easy to learn, easier to operate on.I heva heard about "R", However I understand that "R" is designed especially for statisticians. As an economist, working on applied econometrics, I am not sure if it can meet my needs. Will I be able to reach precise time series or panal data regression results with

Install
Dear Sirs, I am an economist, and I have learned about R from an statician. I would like to get some instructions on which packages of R should I install. I am intending to use R for graphical analysis, correlaction, and also estimation - this latter the least, since I have an econometric package which performes it very well. I should also mention that I am going to work mostly with

getting started on Bayesian analysis
I am an economist who decided it's high time that I learned some Bayesian statistics. I am following An Introduction to Modern Bayesian Econometrics by T. Lancaster. The book recommends using BUGS, but I wonder if there are any alternatives which are free software and fully integrated to R (which I have been using for more than two years for numerical computations.) I would like to learn

FW: oplock break on excel files using samba 2.2.4
I'm having the same kind of problem too. Links to other excel workbooks are really breaking badly. One of them so bad that if I highlight the file through a windows explorer view; it kills the window immediately. I'm using RH 7.2 and Samba 2.2.4 -1 Please let me know if someone has some suggestions .... So far I've tried: veto oplock files = /*.mdb/*.MDB/*.ldb/*.LDB/*.xls/*.XLS

Generalized Lambda
Anyone know of a package for numerically estimating lambda(3) and lambda(4) using location, position, skew and kurtosis estimates. I have a distribution and would like to use the gld package to do some simulations of the distribution, but need the lambda estimates to feed into gld. I have a program in Maple, which I may convert to C code for use in R, but before moving down that road I

Copy-paste graphics from R to Word on Mac OS X
Greetings: I'm (very) new to R. One of the features of R that I really like is R's ability to quickly generate very good looking graphics. However, I've noticed that when I attempt to copy and paste the graphs from the R graphics output window into Word (in Mac OS X), the resulting picture is very jaggy. I'm aware of the various options such as dev2bitmap, but I'd

Tobit analysis
Having read previous correspondance on this topic, am I right in using a gaussian distribution for a tobit model, one article suggests a normal distribution? Also, I want to censure at the upper bound, so, using the survival5 package I use: survreg(Surv(y,y<c,type="right")~x) for a censored regression. Could anybody who's had experience of this, confirm whether I'm in the
