The long-term coefficient of variation using the Hologic phantom was 0.31%.
We take their values in the last available year of the sample, 2011, to construct a happiness index where the estimated long-term coefficients are used as the respective weights of the happiness determinants discussed in the previous section.
Long term decline coefficients were modified by the occurrence of a severe asthma-related event (SARE), based on the definition of SARE and coefficients presented by O'Byrne et al. (Table 2, [ 40]).
For example, the coefficient c9 is zero for complaint categories that do not exhibit linear long term trends, and the coefficients c10 and c11 are zero for categories which do not exhibit seasonality.
Significant long term test-retest correlation coefficients for the wake-time variables with a mean inter-test interval of 22 months (range; r = 0.59 - 0.81) have been reported [ 25].
Long term spine phantom in-vitro coefficient of variation (CV) for the whole period was 0.62%.
13 The alcohol estimates based on the food frequency questionnaire in 1987 and used in long term analysis had a correlation coefficient of 0.9 in comparison with four one-week weighed diet records (three to four months apart).
Benchmark chromophore C1 and counterpart chromophore C2 with the same electron donor and acceptor was designed and synthesized to compare their different electro-optic coefficients and long term stability by doping system.
In the long term, the observed intra-assay coefficients of variation were less than 7% for aldosterone and no more than 5% for cortisol.
In this regard, for the debt ratio in the long term, the negative sign of the coefficient confirms its negative impact on the levels of indebtedness of Tunisian firms.
