Hi Kunal,
I can't speak about the last error with the information provided, but the
previous two error messages are indicating that nptxy and tval are not
attributes of the rc array. You are creating the rc array similar to the
examples on the regCoef documentation page like this correct:
rc = regCoef(x,y)
df = rc at nptxy-2 ; degrees of freedom
tval = rc at tval ; t-statistic
prob = betainc(df/(df+tval^2),df/2.0,0.5)
If you have any further questions please reply to the ncl-talk email list.
