Re: How to fit data with a straight line
Hi,
The following is the whole process to do regress for T
Suppose I have a 3-D data temperature with 49 year x 12 months = 588 time steps
currently SET data sets:
1> temp.nc (default)
name title I J K L
TEMP COADS SST 1:97 1:57 ... 1:588
yes? def axis/t=1-jan-1945:31-dec-1993:365.25/units=days/edges tax1
yes? let TMEAN = TEMP[gt=tax1@ave]
yes? let q = TMEAN[L=1:49] ! Better to specify the time range
yes? let p = t[GT=tax1,L=1:49]
yes? go regresst ! Do not use: set grid q
yes? contour/l=20 QHAT
yes? contour TMEAN[L=20]-QHAT[L=20] ! do not use: contour/L=20 TMEAN-QHAT
Have a good weekend.
