About the residual of calibration points

[william_wong]

Nice to meet you, everyone.
It's my first time to visit here.

I have a problem about setting the acceptant criteria of residual of calibration points. I have no idea to set an appropriate percentage of residual to satisfy the accrediation body. Or is there reference document that I can use?

Thanks and best regards.

I don't believe that there *is* one. That is subsumed in the r2 value. The *distribution* of the residuals is more important.
