For the job strain variables, we imputed missing values with a mean value calculated from the other items included in the job strain scales for those with missing data on at most two items of five for job demands (2.7%), five items of 10 for job control (3.9%) and three items of the six for physical job strain (13.0%).
The removals of NO3 − N were recorded varying from 1 to 88% throughout the 13 runs with the mean value calculated to be approximately 60%.
To do so, we used the data of one dog for which no errors were identified at all, and either randomly deleted 1 %, 2%, 3 %, 44 %, and 5%% of the values or replaced them with a mean value calculated from the preceding and subsequent five values.
For the ensembles of networks encompassing 5 to 8 TRs, box plots with mean values (calculated from 15 values in total for each ensemble analyzed) of epistatic coefficients of second, third, fourth and fifth order, were constructed.
Table 4 lists mean ranges for GEDVI values calculated with the final multivariate model according to the age groups defined for univariate analysis.
Mean and standard errors of experimental values calculated with using Prism 5.0 (GraphPad software Inc .. Statistical analyses comparing the mean of paired experimental groups were conducted with Student's t test using Prism 5.0 (GraphPad software Inc .. Data were considered significantly different when p-values <0.05.
Mean gray value of the signal intensity and standard error of the mean value were calculated with SPSS10.0 for Windows package (SPSS Inc., 1999).
Mean values were calculated with 13 29 independent images (cells) from two biological replications.
In all the figures mean values were calculated with standard deviation (STDEV) until unless stated otherwise.
Mean values were calculated with the localities with more than 4 individuals only.
The mean values were calculated with SD from at least three experiments (>30 plants/line).
