Without sampling the data set is highly imbalanced, while sampling should improve the accuracy since the training data sub-samples fitted to the model are balanced.
There is no significant single marker or pairwise segregation distortion in this population indicating that the model is balanced for all markers (McKay et al., 2008).
The stoichiometric relationships among the metabolites and the reactions of the E. coli genome-scale metabolic model were balanced under the pseudo-steady state assumption.
It is proved that the power law asymptotics appears if, and only if, the model is balanced, i.e. domain duplication and deletion rates are asymptotically equal up to the second order.
Also, the choice for a more complex model should be balanced by any change to the results compared to use of a simpler model [ 33].
Consequently, the ketolide-use benefit predicted by the model should be balanced by the incidence of severe adverse effects.
The number of parameters in the model must be balanced with the amount of data.
Concerns about limitations on discovery using xenograft models must be balanced in light of the absence of an ideally representative OVCA animal model, as well as the relevant clinical pathophysiology being investigated [40], [42].
Since the treatment indicator was non-significant in all these models, we concluded that the selection bias had been successfully removed, and our subsequent models would be balanced (Dehejia and Wahba 2002).
Provided that computers and the required software are available in the ICU, the simplicity of scoring models must be balanced against greater discriminatory power and better calibration of more complex linear and nonlinear models.
