Hello!

The code below create a graph of Mean vs Desviation Standard, I am trying to put a Regression Line like a Fit Line in the resultant graph, but I cann't.
I was wondering if you could help me with this code.

Thank you so much.

Code: Select all

sample ss

scalar n = 99
scalar s = 12
genr x = clients

genr media = 0
genr dt = 0
for !i=1 to n
	if !i * s > n then exitloop endif
	%1 = @otod( !i * s - s + 1 )
	%2 = @otod( !i * s  )
	smpl %1 %2
	media(!i) = @mean( x )
	dt(!i) = @sqrt( @var( x ) )
next
smpl @all if dt > 0

scat media dt

smpl ss
delete dt media n s x ss
