Traditionally, accuracy of an instrument is defined as the sum of the precision and the bias.
First a procedure for the AACMM verification with the indexed metrology platform (IMP) and the laser tracker (LT) used as a reference instrument was defined and the required accuracy of the equipment was assessed.
In particular, the threshold instrument is defined as a binary variable that equals 1 when the municipality in which an individual lives is more than 4200 m away from its MDF (lower probability of DSL availability) and 0 otherwise.42.42
One option could be, for example, to resort to a dictionary definition, with the Oxford English Dictionary (OED) offering: "any instrument of manual operation", where instrument is defined as an "object used for a given purpose".
The date on which the first LC-MS/MS was conducted for each instrument was defined as day one.
Evaluation in this instrument is defined as "the process of using data to assess group/team performance and to achieve outcomes in organizations or units" [ 40].
We investigate this here by estimating multiple IV models in which – each time – the instrument is defined by a different set of SNPs.
ROC-analysis was performed to evaluate the screening properties of the SSI, and the cutoff threshold for the instrument was defined by optimal trade-off between sensitivity and specificity (Youden's index [ 31]).
In general, the minimal clinically important difference (MCID) of a PRO instrument is defined as smallest change in a PRO measure that is linked to a clinically relevant difference or change.
Responsiveness, or "sensitivity to change", an essential property of measuring instrument, is defined as the ability to detect a clinically meaningful change [ 9- 12], such as a change that clinicians or patients think is discernable and important.
