Counting Without Seeing
Mathematics and Engineering
The National Park Service asked for an estimate of the number of elk taken by the wolves introduced to the park. As there was no method guaranteed to find all the kills in the wilds of the park, a design was created to estimate what was not seen. The estimate involved a double count procedure, logistic regression modeling and parameter approximation. Once the estimate was found, the search and verification of the standard error involved delta methods, bootstrapping, and simulation.
