errors-in-variables routin? [message #50139]

Hello There,

I have this problem: I can't find any IDL fitting routins that can do
miltivariate linear regression with errors in the independent
variables, i.e. to fit the observed Y with the function
F=a0+X1*a1+..+Xn*am, when the n-element vectors Y,X1...,Xn are all
subject to observational errors (Xs are also some observed quanities).
The parameters to estimate are a0,..,am. There are tons of theoretical
articles, but not practical implementations. The IDL regress allows
only errors in Y. Can somebody help?

Regards,
Vallery
