For each set of assays a standard curve using pure ATP (Sigma, St . Louis MO) in serial dilutions was carried out to overcome any experimental variances, operator differences, and instrument discrepancies, etc.
A careless or tired operator may be inclined to ignore discrepancies or may repeat the same mistake.
We conducted computer logical checking and also manual checking, particularly when there were discrepancies between the two operators.
The discrepancy suggests operators are pocketing the difference, €2.11, as profit.
The presence of this bias raises the question of whether this average discrepancy between operators (i.e., the bias) is of clinical importance (i.e., if the intra- and interoperator variability of measurements are greater than the variability due to differences among gestational age groups).
We have used for this work a SIRT-type iterative approach to find a solution for Eq. (11); the weighted-backprojection operator (bar{mathcal{R}}^*_Gamma) being used to correct for the discrepancies at each iteration.
It is not clear if this degree of discrepancy is to be expected when a skilled operator takes two tympanic readings, or if it was a true difference between the two types of tympanic thermometer.
Earlier in the day, during cross-examination, Mr. Del Col had pointed to discrepancies between what Mr. Estrada told a detective and a 911 operator last fall and what he told the jury -- for instance, which tools the assailants had used.
Remark 2.3 The generalized discrepancy principle for regularization parameter choice is presented in [15] for the ill-posed operator equation (4) when A is a linear and bounded operator in Hilbert space.
Regardless, to evaluate the possible clinical relevance of this average discrepancy between the operators (i.e., the bias), we made some further considerations.
