Dear ALL
I am using regressxy to calculate correlation coefficients over areal average.
when i change the order of p and q , the values significantly varies, yet I thought the order of the variables doesn’t matter
for example when I do like this ...
let p =pr[d=3,x=30E:42E@ave, y=0:5N@ave,l=1:3]
let q =pr[d=1,x=30E:42E@ave, y=0:5N@ave,l=1:3]
go variance
list correl =0.5
but when I reverse the order say ...
let q =pr[d=3,x=30E:42E@ave, y=0:5N@ave,l=1:3]
let p =pr[d=1,x=30E:42E@ave, y=0:5N@ave,l=1:3]
go variance
list correl =0.1
