swirl: Learning Statistics & R

October 29, 2013 | 0 Comments

Most of us would acknowledge that getting up to speed with R involves a pretty steep learning curve - but it's worth every drop of sweat we shed in the process! If you're learning basic statistics/econometrics, and learning R at the same time, then the challenge is two-fold. So, ... [Read more...]

Can Your Results be Replicated?

September 11, 2013 | 0 Comments

It's a "given" that your empirical results should be able to be replicated by others. That's why more and more journals are encouraging or requiring that authors of such papers "deposit" their data and code with the journal as a condition of acceptance for publication.

You Can Quote Me on That

April 21, 2013 | 0 Comments

The other day I came across the Empirical Quotes page on Mark Byran's blog. Some of his quotes related specifically to econometrics, and I thought I'd share a few others.
