Can you break that down by credit grade?
I was doing that for awhile and recently stopped. I stopped because it was a lot of work and I'm not as interested in Prosper as I once was. If I really got a fire built under me, I could write a screen scraper and related tools to do the job but it sounds too much like work and I have other interests. I had some ideas one time to do all this but I just never actually did it. The fact that Prosper keeps changing the data didn't help either. When they changed all those loans in the new agency test from defaulted to repurchased was pretty-much the last straw for me. It's just too much work to go through eric's site to find all the loans Prosper has removed from the data and try to add it back in so I just gave up.
You can see how things looked on the statistics wiki page up to last January or so for the first year of Prosper's existance. If you look at those numbers, you will see the data is very, very noisy early on and I doubt it has changed much since then. If someone wanted to replicate those, it's not really complicated but it is very time consuming. Someday, I might get inspired and create that screen scraper but for now, I just don't feel like it. I've got better things to do.
