To date the coefficient of acceleration varies between 1 and 70 depending on the nature of the problem.
To date, solvent coefficients have been determined for over 90 commonly used solvents (Additional file 1), and group contribution methods have been developed to approximate all coefficients for certain classes of solvents that do not have published solvent coefficients [25,26].
We found that the year of publication for the primary report was closely correlated with the year when the trial commenced for the 141 trials which contained complete information for both these dates (correlation coefficient = 0.89) and, so, we used the year of publication of the primary report as a proxy measure for the year in which the trial commenced in the full dataset of 191 trials.
To date, the coefficients needed to adjust for productivity differences between the various regions are available only for a few countries.
The collisional reactions have up-to-date rate coefficients from Le Teuff et al. [Le Teuff, Y.H., Millar, T.J., Markwick, A.J., The UMIST database for astrochemistry 1999, A&AS, 146, 157 168, 2000.], while the photolytic rate coefficients were taken for minimum and maximum solar fluxes in order to estimate an lower and a upper limit for the abundances of NS and CS.
To date, the constant correction coefficient Aeff(7) is used to account for lateral diffusion in DGT measurements.
We observed a statistically significant inverse correlation between the occurrence of misplacement and the patient number i.e. the date of operation (correlation coefficient of –0.35; p < 0.001).
For dates, we computed the coefficient of variation (C.V .. Analyses were performed using the SAS statistical software package (Release 9.1, SAS Institute Inc., Cary, North Carolina) and R [ 15].
The sign of the coefficient for thaw date is negative, indicating that if the thaw date occurs later in the year, then the number of cases of AIV is predicted to decrease [Table 3, for details see [ 67]].
To date, reliable markers with low coefficient of variation (CV) are generally lacking.
All effects of inbreeding were due to the offspring inbreeding coefficient, but birth date showed no clear evidence for inbreeding depression.
