Thus, problems arise when attempts are made to model plague-flea-rodent systems, which require parameter estimates for important processes (6, 7, S. Park et al., unpub. data), or when these models generate parameter estimates that cannot be checked against independent values more directly derived from field data (S. Park et al., unpub. data).
Sensitivity analysis showed that correcting source tracer data for differences in organic matter can produce large changes to source contribution estimates that cannot be justified, and such corrections should not be used.
Given their estimated employment elasticity for those in the bottom decile of the skill distribution (the affected workers) of −0.076, and an employment rate in this group of 44%, the employment effect implied by the increase they consider is −6%, an estimate that cannot be used to dismiss the methods out of hand as providing implausible estimates.15.15
The major advantage of stochastic sampling is that it provides a generic and convenient means to estimate quantities that cannot be easily computed directly by backwards recursion (Ding and Lawrence, 2003).
We also tested a matrix factorization-based approach to determine whether mixture proportions estimated by deconvolution algorithms (that cannot estimate individual cancer profiles [ 14, 20, 21, 26- 32]) could still be useful for prognostic prediction.
LBA also estimates the time that cannot be explained by any of the other components (nondecision time Ter).
More complex phylogenetic models have been developed to estimate epidemiological parameters that cannot be achieved with parametric coalescent models alone [ 22– 25].
In July 2011 the council got £74,000 for A Somnambulist – a figure beneath the auctioneer's estimate, and a sum that cannot possibly have made any serious difference to Bolton's finances or plans for a new city art store.
Therefore, studies that used type IV monitors, which cannot differentiate between obstructive and central apneas, devices that cannot estimate the apnea hypopnea index (AHI), questionnaires, or self-reported snoring to assess OSA were excluded.
Based on structural model and available experimental data, parameters identifiability procedures partition the original set of parameters into two subsets: (i) the parameters that can be estimated, called identifiable parameters, and (ii) the parameters that cannot be estimated, called nonidentifiable parameters.
Inherent safety, safety factors, and multiple barriers have an important common feature: They all aim at protecting us not only against risks that can be assigned meaningful probability estimates, but also against dangers that cannot be probabilized, such as the possibility that some unanticipated type of event gives rise to an accident.
