Hi,all,
I posted this question couple of days again, but haven't gotten any answers
back. I would like to post it again, and if you have any ideas, please let
me know. Any helps and suggestions are very much appreciated.
Start by reading the Posting Guide.
It will tell you to
*) Do RSiteSearch("keyword") with different keywords (at the R prompt)
to search R functions, contributed packages and R-Help postings.
and
RSiteSearch("measurement error")
gives a number of hits that might be of interest.
If these hits do not pan out, you should let us know why none of the
available packages that have 'measurement error' in their descriptions
satisfy your needs.
HTH,
Chuck
The problem is about linear regression with both y and x have measurement,
and the variance of errors are heterogeneous. The estimated regression
coefficient and its variance are of interest. Is any R package doing this
task ?
Thank you
