For true accuracy, it should only come in the passive voice.
In contrast, when true accuracy (d′) varies, the pAUC for both showup and six-person lineup identifications capture those changes quite readily.
Thus, the highest-confidence and most important region of the showup and six-person lineup ROCs are visually indistinguishable when true accuracy (d′) is equated.
Our analyses demonstrate that the two paradigms yield essentially identical estimates of performance when the true accuracy level (d′) is equated.
This approach may therefore misrepresent the true accuracy of the land cover product, as well as the accuracy of the validation data, which is not assumed to be without error.
The statistical noise will be smaller if the sample sizes are increased in (future) multicentre studies in order to assess the true accuracy of MRI in the NAC setting with greater confidence.
Future work should include the use of virtual phantoms where the true activity distribution is known followed by imaging simulation and application of VBDM to estimate true accuracy of such methods in patients.
Figure 2 shows that with a true accuracy difference of 1.0 d′ units, pAUC changes are obvious for both showup and lineup decisions (i.e., approximately twice the size of the larger gray square in Fig. 1).
Formal errors on Gauss coefficients, calculated from the covariance matrix and the a posteriori estimated data error, are not helpful to assess the true accuracy of our model with respect to an arbitrary and independent dataset.
The aim of this study was to evaluate the "true" accuracy of a flat panel single plane video-fluoroscopy system based on computed-assisted design (CAD) model matching and compare it to TKA kinematics obtained from optoelectronic measurements as gold standard.
Figure 2 shows that the difference in pAUCs for showups and six-person lineups is trivial when true accuracy (d′) is equated.4 The differences typically appear in the fourth decimal place (i.e., less than the size of the smaller gray square in Fig. 1).
