[gradsusr] Linear Trend Analysis using Grads

[Tereza Cavazos]

Hi,

I found a script to calculate linear trends and its significance in 
Grads by Dhaval.
I wonder if anyone has written a script to calculate the trend using the 
Mann-Kendall test and/or Sen´s test for the significance of the trend.

I will appreciate any help.
Cheers,

Tereza
