This is the undelaying idea of questionnaires like the SEIQoL, a method which values the HRQoL from the individual perspective [26].
The approach used to value care hours was the proxy good method, which values time as an output and values the care provided by the informal caregiver considering that if they did not provide these services, their presence would have to be substituted by a professional caregiver who could provide them [ 25].
Swedish guidelines recommend the use of the traditional human capital (HC) method, which values lost productivity in terms of gross earnings, whereas the Canadian, Dutch, and Australian authorities recommend the friction cost (FC) approach, which focuses on the time required to restore the lost productivity due to the absent worker.
The other method was the DC-polarization method, which gave values from 0.31 at 0.1 mole kg−1 to 0.72 at 2.1 mole kg−1.
One method for transference number measurements was based on the Hittorf method, which gave values ranging from 0.15 at 0.1 mole kg−1 to 0.31 at 2.1 mole kg−1.
The aim of this study was to determine, when using the CVT method, which parameter values of acquisition, reconstruction and analysis maximise the separation between the activity distributions in the lungs of healthy subjects and in the lungs of subjects with mild COPD (small heterogeneity variations).
This coefficient was determined with the Sum method, which adds values of signal over background for all genes on arrays.
Any outliers present in ELISA readings were determined using Tukey's method which considers values at a distance of 1.5 times the interquartile range (IQR) below Q1 (quartile one) or at 1.5 times the IQR above Q3 (quartile three).
Any outliers present in ELISA readings were determined using Tukey's method which considers values at a distance of 1.5 times the interquartile range (IQR) below Q1 (quartile one) or at 1.5 times the IQR above Q3 (quartile three) to be a possible outlier.
We accounted for the missing values using the hot deck method, in which values are generated from other observations in the sample that have similar characteristics.
