For the estimation of precision, duplicate scans obtained on the same day for nine women were analyzed using both versions of the software.
For this reason, we inferred these hyperparameters from the dataset for various levels of expression, prior to the estimation of precision λ m and mean expression μ m.
Firstly, for head repositioning, the number of trials performed for each movement direction has been reported to affect the estimation of precision and accuracy, with an increasing test stability (i.e., higher ICC values) attained when a larger number of trials are performed (five trials or more) [ 50, 51].
In this case, estimation of precision can be performed before implementation (eg, ±1 bp), whereas trueness is dealt with by running a standard curve with each experiment (ie, a size standard).
We also discuss possible biases caused by the temperature dependence of the absorption cross section utilized in the DOAS retrieval, and the effect of uncertainties of surface albedo and clouds on the estimation of precisions.
For the subject illustrated as an example, the average of the estimations of precision was 0.43 mm.
We are aware that this type of automatic evaluation suffers from false negatives, but it provides a realistic estimation of precision without requiring expensive manual evaluation.
The width of the SD of the mean difference is an estimation of precision.
An important issue with such methods is that they will often lead to a misleading estimation of precision, which is often overestimated.
Given that it was not possible to measure specificity or precision within our gold standard set, a post-hoc estimation of precision was used to gauge the filter's performance under 'real world' conditions.
