I'm answering to myself on the mailing list just in case it might help some
in the future.
As, someone pointed out the error is in the assignment operator:
I wrote in the code:
sum1 =+ (i-mx)*(j-my)
which does not add the values but puts them.
Instead I should have wrote
sum1 += (i-mx)
Hello,
I'm having troubles understand something about regression coefficients.
If I have two vectors:
x = [1.38, 1.98, 3.18, 3.56, 4.9, 6.21, 6.44, 7.47, 8.36, 8.81]
y = [8.19, 17.77, 20.12, 14.55, 20.17 ,31.22 ,28.94, 34.79, 40.26, 38.99]
and I would like to find out the regression coefficient
