Weighted Deming Regression Routines ???

[gkrf...@gmail.com]

Hi, 

I am trying to test for the various linear fitting methods with errors in both variables.

(e.g. Deming Regression, Williamson York) 

I just find 'fitexy' function from Numerical Recieps. 

 

Is there any libs. for weighted Deming Regression in IDL?

or someone can help this?

Best, 

Haklim
