Bug ID: 471174
Summary: "Use given data uncertainties" option has no effect
Classification: Applications
Product: LabPlot2
Version: 2.10.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: backend
Assignee: alexander.se...@web.de
Reporter: jf.mun...@gmail.com
Target Milestone: ---
SUMMARY
When doing a fit, checking "Use given data uncertainties" on fit options has no
effect.
STEPS TO REPRODUCE
1. Create a fit, making sure the spreadsheet has a column for the Y
uncertainties.
2. Now disable the "Use given data uncertainties" option, re-run the fit, and
compare the results
OBSERVED RESULT
Nothing changes.
EXPECTED RESULT
For instance, one would expect the uncertainties to influence the χ²
calculation, since we should be dividing each squared residual by the variance
of each point, which changes according to its uncertainty.
