Number clutter. When you do as much data analysis as we do here at Political Calculations, you'll eventually have to deal with the problem of what to do with all the data.
One way we deal with number clutter here at Political Calculations is to model it using mathematic equations. A simple, or maybe not-so-simple, equation can go a long way toward our not having to bog down our computer's memory with reams and reams of numbers. Being able to define data with a mathematical relationship instead of maintaining individual data points makes a lot more sense and helps speed up our analysis process. Plus, we can make some neat tools using the relationships!
So, when you deal with as much data as we do, you *really* appreciate when you find tools that make handling that data much easier. The neatest, coolest, most useful application that we've ever stumbled across on the web does just that. It's called ZunZun and it fits curves to data online. But that's not all - not only does it handle ordinary garden-variety 2-D datasets, it does 3-D data too!
With any luck, our data clogging days are over!
Speaking of data - the New Economist points to 98 ways to visualize data!
Welcome to the blogosphere's toolchest! Here, unlike other blogs dedicated to analyzing current events, we create easy-to-use, simple tools to do the math related to them so you can get in on the action too! If you would like to learn more about these tools, or if you would like to contribute ideas to develop for this blog, please e-mail us at:
