    So I see you’ve got something like a modified Gaussian (though the exponent doesn’t seem to be 2) — and you’re fitting some kind of distribution to it.

    What’s that data you’re fitting?

    Sorry for the confusion. These are normalized S&P500 daily returns over some 50 years. It’s for my other “hobby,” mechanical investing. I needed a place to post a quick picture.

    I can’t help it, Daryl: that’s just like the legendary Bell Curve…

    It’s close. In a Normal bell curve e=2 by definition. This is a modified Gaussian.

    Hmmm, doesn’t seem to fit the tails very well. I’m doing a similar thing for my job right now (and yes, it’s a mechanical investing product). I was going to try a Weibull r.v.

    MP,
    I’d love to talk to you about MI. Drop me an email.
