Although only a small proportion of the total variation in the example data set is due to non-additive effects, a low order factor analytic model assuming independent genotypes still improved the goodness of fit.
Indeed, if we were to consider absolute variations – in the case that, for example, one output signal presented a much higher variation than the others – the behavior of the whole sensor would be dominated by this one, affecting the capability to properly distinguish the three force components.
The aim of statistical modelling is to identify the main factors that explain variation in the outcome for example, patient and practice characteristics.
They acknowledge the potential pitfalls of translating survey results into 'real life'; however, my own experience of the diversities within UK practice suggest this would be representative of at least one other industrialized country, albeit with some variation in the detail (for example, use of gelatin as a plasma expander is much commoner in Europe).
Variation in the pelvic bone, for example, is described as [29]: "Shape of ischiac process: small or posteriorly elongate (0); falciform (1); falciform and strongly developed (2)".
There was a profound sampling variation in the included studies, for example: One study group chose to set up inclusion criteria for the GPs' participation in the study [ 9].
A range of risk prediction tools including the Combined Model [ 10] developed for NHS England, and QAdmissions [ 11] are intended to produce stratified lists of patients, but there is some variation in the underlying modelling (for example, whether or not secondary care data is used alongside primary care data).
Synapses in EM images may be angled at any 2D orientation, which may add undesirable variation in training examples.
Compound pistils are thought to have arisen as a result of crowding of simple pistils on the floral axis; for example, variation in the degree of fusion may be observed in members of the saxifrage family.
A variation in the HLA-G gene, for example, was identified in a subset of female prostitutes who had remained HIV-negative despite having had sexual contact with more than 500 HIV-positive men.
