Standard deviation has been widely used as a way to calculate diameter and height complexity and can be compared with more complex indices for stand structural comparisons (McElhinny et al. 2005 and citations within).
In all groups assessed in our study, fasting insulin had comparable correlations to those observed with the more complex indices of insulin resistance (HOMA-IR, QUICKI or FIRI) with clamp insulin sensitivity.
More recent publications (e.g., Jin et al., 2015; Rücker et al., 2011; Schwarzer et al., 2010; Stanley & Doucouliagos, 2014; Stanley & Doucouliagos, 2015) have urged the adoption of more complex indices of selection bias: 1.
In general, the spatial inhomogeneity of PWV started increasing before the observation of strong radar echoes within the GPS observation area, suggesting the possibility to use it as an index to predict precipitation events or at least as a parameter within a more complex index including other meteorological observations.
23 Use of both measures allowed consideration of whether the more complex index added predictive value over a simple count of professional groups.
In a forthcoming study, we demonstrate the building of a more complex index based on these principles, which is expected to satisfy additional and more stringent tests of construct validity.
Many more complex meteorological indices depend on windspeed as an input, which limits their application to the calculation of index values at the location of sophisticated weather stations (the approach taken by Arpaci et al., 2013).
When the organisation of production becomes more complex, productivity indices become less relevant for the evaluation of performance, since the overall performance is less related to the optimisation of transfer of goods in space and more and more to the functioning of relations throughout the supply chain.
In addition, since microbubbles are vascular tracers, following a bolus injection, their passage through a tissue of interest can be quantified to generate time intensity curves from which many functional indices can be derived, including bolus arrival time, time to peak intensity, area under the curve, wash in/out curves, as well as more complex deconvolution indices.
We chose here the Angström, Nesterov and KBDI indices to represent a continuum of fire index types from a simple instantaneous index, to one that includes consideration of precipitation, to a more complex accumulative index with a physical interpretation.
In a recent study a compact frailty index with three components performed as well as a more complex frailty index with five components in predicting falls, disability and mortality [ 17].
