In eCerto: Statistical Tests for the Production of Reference Materials
Homogeneity
Homogeneity statistics
The uncertainty contribution of the Homogeneity measurements u_bb (uncertainty between bottles) is calculated
for each analyte based on variance obtained by an ANOVA and is transferred to a user specified column in
the material table of the certification module (Tab.C3).
Note!
Values for u_bb can be transferred to Tab.C3 in case that matching analyte names are present
(analyte names are depicted in red if not found).
Homogeneity report
Figures and tables can currently be exported in HTML format.
Note!
Report layout and format are currently under debate and might change in the future depending on user demand.
