Speed of mean reversion

Hi!

I'm wondering how to calculate the speed of mean reversion. I've heard that the half-life formula is t = ln(0.5)/ln(abs(b)).

But how do you use it in practice? I'm quite lost here.

Best regards,

Maurelius

What I want to know is how to estimate the Ornstein-Uhlenbeck process for a time-series data of stock prices. Anyone please help?
