Factors that influence the accuracy of acoustic density estimates depend on the estimation method chosen, but generally include small variance in the parameters that make up the density estimate.
Intuitively, both pan and core genome size estimates depend on accurate estimation of the frequency of rare events that any small sub-sample of sequenced genomes will not enable.
And it's not just the developing countries that become dependent: around 500,000 people, Moyo estimates, depend on disbursing aid for their livelihoods.
BUT the estimates depend on the success of the Xbox.
(Estimates depend on the time period, the income tiers and the definition of inequality).
Estimates depend in large part on information derived from secondary sources, but also draws upon the limited survey data that is currently available, as well as expert assessment.
But it said many weapons projects start out with unrealistically low cost estimates, depend on technologies that are not ready and face constant changes in design requirements.
In the report the IPCC highlighted that cost estimates depend on a variety of assumptions, including the availability of relevant technologies and co-ordinated international action.
As he himself notes, the FEER estimates depend heavily on assumptions about what counts as a current-account balance that can be sustained in the long run.
Many studies, including those by the Government Accountability Office and Pentagon boards, have shown that many weapons projects start out with unrealistically low cost estimates, depend on technologies that are not ready and face constant changes in design requirements.
More importantly, however, it must be remembered that both sets of figures are estimates.Ultimately such estimates depend on choices that are to some extent subjective, and in the absence of error-free data there will always be substantial uncertainty.
