[ncl-talk] regCoef_n without y-axis intercept

[Giorgio Graffino]

Hi Dennis, Dave

Thanks for sending the relevant function and for explaining how to 
access the source code. Now I'm thinking how to make the function to 
force the regression to pass from origin. Any idea on how to do that?

Cheers,
Giorgio

Hi Dave,


Thanks for the advice. I looked at the examples in 
https://www.ncl.ucar.edu/Applications/regress.shtml 
<https://www.ncl.ucar.edu/Applications/regress.shtml> , especially 
examples 2 and 4, but I couldn't find any supplementary information 
about regCoef. I also can't find anything under 
$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl and 
$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl.

Is NCL source code located anywhere in $NCARG_ROOT? Can anyone please 
point me where it is?

Cheers,
Giorgio

Giorgio, for your second question, please see this very brief 
description that I recently wrote, for how to search for functions in 
the NCL source code.

Hi NCL community,
I want regCoef_n to find the regression coefficient between two arrays 
without y-axis intercept. Do you know how I can change the function to 
do that?
Can you also please tell me where I can find the function? I did a grep 
recursive search in my $NCARG_ROOT directory but I couldn't find it.
Cheers,
Giorgio
