Matlab - Yahoo Finance Interface (from Matlab File Exchange)

You can also find a code to capture Yahoo Finance data into Matlab at the Matlab File Exchange sute. The code requires Java and the Financial Toolbox.

The file description from the original link follows:
This is the example code for the News and Notes article entitled "Internet Enabled Data Analysis and Visualization with MATLAB." It demonstrates how to use Java to retrieve and plot data publically available on the Internet, using historical stock data from the Yahoo! servers as an example. Note that the Yahoo! historical stock price server is often very busy during the US business day -- you may have trouble connecting. Try again after 4:30pm Eastern (US) Time.

A very interesting blog and blog post for those of us who want to download free financial data into Matlab.
I haven´t looked into his code yet, but it´s always good to have a starting point. Another suggestion is Ernest Chan´s blog on Quantitative Trading.

Creative leading indicators

This is an interesting post from the Economist's site this week. In a nutshell, readers were asked to come up with interesting leading indicators for the US economic activity.

One of the most creative was based on the number of Google searches on the "gold price" string.

Check out the original article at the link below.

Excel substitute

I just came across a wonderful link at the Statistical Consultants group on Linkedin. I haven't tried yet but it´s definitely worth the shot. It is a free Excel substitute - you might say "useless", there are dozens out there. The catch is - it seems to do the hard stuff very well, that is, it seems to overcome all the known problems Excel has regarding random number generation and statistical procedures.

The product is called Gnumeric, it is free and you can get it at:
A report with Excel´s problems is at:

the first one....

What is this blog for?
The idea is to complement my site in a more dynamic (and I grant it, disorganized) format.

The primary objective is to share interesting links, posts and ideas.

Obviously, you may not agree with my definition of "interesting", but here you´ll probably see comments and links on Finance, Economics, Computers, Statistics and some things on the lighter and brighter side.

Hope you enjoy.
