An alternative future direction for correcting sample selection bias would be to develop models of population structure that can also model the auxiliary factors such as geography or language that may determine the selection process responsible for the biased sampling.
We introduce the concept of nutrient load as the product of local patch nutrient concentration and predicted that relatively efficient nutrients in fluctuating nutritional environments may determine foraging patch selection in giant pandas.
This selection may determine work location decisions, independent of any effect the medical school characteristic may have on participation in financial-incentive programs.
To the contrary, we have suggested that uncertainty influences cortical inference and learning through other neuromodulatory systems [ 24], and that it also may determine aspects of the selection of actions [ 25].
This suggests the possibility that many of distressed patients are uninterested in services, despite encouragement for them to seek them, and that some wisdom of self-selection may determine which patients will seek services and benefit from them.
In a merged beam experiment, three factors may determine the transverse spread: the geometric selection of the components of the beam that are fed into the guide, the acceptance of the guides themselves, and the geometric selection between the end of the guide and the interaction region.
The selection of panellists may determine the range and nature of views expressed in the surveys [29].
Thus the genetic background against which a mutation arises may determine whether it is favored by selection, and therefore whether it sweeps to fixation and increases the average fitness of the population as a whole.
Further study may determine the role of this variable added to the current predictive model for selection of adjuvant therapy.
An in vitro selection assay of human immunodeficiency virus elements suggested that structure, rather than specific sequences, may determine the poly(A) site location [ 19].
