This result is controversial to that reported by Mathur et al. [16], who reported negative values of S for PSi layers, formed also by anodization of p-type Si, as in the present work.
As described previously by Berkowitz et al. (2003), we used all observed positive values of o,p′ -DDT in analyses, even those reported to be below the limit of detection (LOD); seven o,p′ -DDT measurements with reported negative values were recoded as the lowest measured value (i.e., 0.01 μg/L).
The straightforward interpretation of QR is changed in Q'R, the version the author describes as being scaled between 0 and 1, only to report negative values later on in the paper (Fig. 2).
Such approaches would classify 10%to20%0% of chest pain presentations as low risk [8],[9] and have reported negative predictive values exceeding 99%.
We also report negative predictive value (NPV) [ 16], which gives the rate of prevention of the DP of VAS 3+ tenderness of tennis elbow.
Two of Blackstone's other core businesses, its real estate and hedge fund operations, also reported negative revenue as they wrote down the value of their holdings.
Therefore, PEM controls for the fact that some genes are highly expressed across many tissues (housekeeping genes), and has the virtue of reporting a negative value for under-expressed genes, and a positive value for over-expressed genes.
We report negative log-likelihoods (smaller values indicate better fit), penalised for model complexity using the Bayesian information criterion (BIC) (Schwarz, 1978).
Two blood lead values that were reported as negative values were converted to the instrument LOD divided by the square root of two.
Although our findings were published in journals that recognise the value in reporting negative findings, we have found that members of the wider scientific community are less accepting.
