- Title
ESTIMATION OF POPULATION GROWTH AND EXTINCTION PARAMETERS FROM NOISY DATA.
- Authors
Lindley, Steven T.
- Abstract
The article presents a study on the use of random-walk-with-drift model to noisy time series of population estimates of California sea otter and Yellowstone grizzly bear data in 2003. It shows that California sea otters seem to have little risk of extinction, even though the population might not be secure over the long term if population growth cessation persists. It reveals that the grizzly bear population seem to have positively responded to the 1988 Yellowstone fires.
