standard errors for orthogonal linear regression
...that can rankle.) I tried to imitate what's done in the code for lm() but went astray somewhere and got nonsense.
(This type of modeling goes by several names: total least squares, errors in variables, orthogonal distance regression (ODR), depending on where you are coming from.)
I have found ODRpack, but I haven't yet plowed through the Fortran to see if what I need is there; I'm working on it....
Thanks!

Errors in Variables
I hope somebody can help.
A student of mine is doing a study on Measurement Error models
(errors-in-variables, total least squares, etc.). I have an old
reference to a "multi archive" that contains
leiv3: Programs for best line fitting with errors in both coordinates.
(The date is October 1989, by B.D. Ripley et al.)
I have done a search for something similar in R withour success. Has

Sorry, for disturbing the list again.
> Also I got one suggestion of using ORDPACK at http://www.netlib.org/.
It's ODRPACK at http://www.netlib.org/, not ORDPACK.
Best,
