Hey Ladies and Gents,

I have a time series data of daily wind speeds. How can I extract the volatility, standard deviation, and drift of this data-set. I want to be able to use these parameters to model the wind speed as Geometric Brownian Motion and create forecast models.

You first need to define what you mean by volatility, as opposed to a noise standard deviation.
