Is my calibration linear?
Abstract
Testing for the linearity of the calibration is an important feature in the development of an analytical method. The correlation coefficient is often used in this context but is open to misinterpretation by the unwary and is to be discouraged. When data are collected in well designed calibration experiments, tests for non-linearity can be based on the analysis of the residual variance from a regression into parts owing to ‘lack-of-fit’ and ‘pure error’. The calculations can be executed by means of a few simple commands in many statistical software packages.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
