- Subject: non-linear curve fitting tool in grace returns rms relative error instead of rms percentage error
- From: Alex Valavanis <eenav@leeds.ac.uk>
- Date: Sat, 20 Jun 2009 11:40:54 +0100
- Message-id: <1245494454.6595.7.camel@lepton>
Package: grace
Version: 1:5.1.22-2
Severity: normal
The non-linear curve fitting tool in grace outputs the wrong value next
to "RMS per cent error:" It actually gives the RMS **relative** error,
i.e. it is out by a factor of exactly 100.
The RMS per cent error should be given as:
e = 100 * (y'-y)^2/y^2
* Patch attached for source code
