IpeaGeo - Spatial Econometrics Software

IpeaGeo is the new spatial econometrics software developed by the IPEA team. It is free (as in free beer), user friendly and it does spatial GMM, spatial clusters and much more. Strongly recommended. Unfortunately it is only available in Portuguese.

Another good reason for using R

Penn World Tables are available as an R package. Further news on R and econometrics are available here.

New movies

• Moon (2009)-a retro sci-fi movie. Kevin Spacey is the voice of the computer Hal Sam.
• The invention of lying - At first glance, it is another feel-good movie from Hollywood. It is not. Thanks, Ricky Gervais.
• Flood with love for the kid. A one man remake of do Rambo First Blood (!?!?!?). The critics say it is great.

Bonus track: how to watch Daily Show and the Office outside the US.

Netbook and Windows 7

Surprisingly, Windows 7 runs quite well in my new Lenovo S10-3t with only 1G of RAM.

R packages every social scientist must have

Great list!

Netlogo

My friend Bernardo Furtado convinced me that Netlogo is pretty cool. He showed me a bunch of impressive simulations, but one really got me: Von Thünen model.

Another reason for using R

It is Hal Varian's choice at Google!

Qgis

Qgis is an open-source alternative to Arcview, specially when you install the plug-ins.

Software Tips

- I gave up Remember the Milk and moved to Google Tasks (5 additional ways to access it);
- Quantum GIS, the open source alternative to ArcView.
- Go-oo, an Open Office upgrade. HT Renato Colistete. (If you use Ubuntu there is no need to upgrade.)

Why Ubuntu?

In order to protect my tired madelung wrists, I gave up my dear T61 and I've bought a desktop and an ergonomic keyboard. Pretty cool machine, but it took me a couple of hours to remove the bloatware from Windows Vista.
Yesterday I installed the new Ubuntu. One hour later, everything was working perfectly, including the microsoft keyboard and the all-in-one printer. It took me 30 extra minutes to install all extra software. (In Ubuntu world you just choose the softwares that you want from a list. It downloads, installs and tracks new versions No need for going to each website and clicking "I accept" a thousand times). Awesome.

Ubuntu 9.04!!!

If Pollock were a graph designer

Forget Andrew Gelman and his clean graphs. The new style is Pollock-esque.
Congratulations to Ian!!!

Whipple's index in R

The index measures the degree of age heaping in demographic data. Joerg Baten have been applying it to appraise the numeracy of historical populations. Surely there is neater way to do it, but here is the code in R that I've just written:

tmp1<-data[data>=23 & data<=62]
tmp2<-tmp1%%5
whipple<-(length(tmp2[tmp2==0])/length(tmp1))*500
whipple

Graph of regression results

Thanks to the R code written by the guys at Tables2Graphs (take a look at the blog of Eduardo Leoni, one of the authors), I've managed to get the graph bellow. It represents the estimated coefficients of a regression concerning the height of workers born between 1889-1921 and registered at Rio Grande do Sul, Brazil.

Ideapad S10 e Ubuntu Netbook Remix

One month ago I bought a Lenovo Ideapad S10. Beautiful, light, small, and fast. I am a very happy owner. The obvious limitations are the size of the screen and keyboard. They are perfect for smurfs, but normal human beings suffer a lot after 3 hours of use.
It came with Windows XP so I was not in a hurry to run Ubuntu. Yesterday, I took a break and installed Ubuntu Netbook Remix, ie, Ubuntu for tiny notebooks. It is perfect and almost solves the screen issue.
