Re: [ferret_users] Calculating Probability Density Function

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Archana, 
You might look at this, making a seasonal mask
http://ferret.pmel.noaa.gov/FERRET_17sep07/FAQ/analysis/seasonal_masking.html

You would need to change the definitions in the examples to get the 
months you want to choose.

Also run this script, which shows how to define probability density 
functions.

yes? go statistics_demo

It creates data on an x axis, and shows how to define statistics on that 
variable ARG.
