[ferret_users] Plotting 95% confidence intervals

[Sarah Bonham <eesb@xxxxxxxxxxx>]

Dear Ferret users,

I have 2 sets of temperature data, both on a 73x96 array and I am  
trying to produce a map of the difference between the two showing only  
temperature values that have a 95% confidence.

Is there a function in ferret to apply a student t-test or something similar?

Ideally, I would just like to map the temperatures that have 95%  
confidence, but if this isn't possible and there is a way to put  
shading over the top instead, then this would be great to.

Any help is greatly appreciated,

thank you in advance,

Sarah
