Batrecapture


In a particular study bats were captured regularly for over an year. About 9000 different individuals were captured and released back, some of them more than once. We assume that all bats are equally likely to be captured regardless of how often they have experienced capture earlier. We have to see if such a model fits the data well. If not, we can try a modification in which probability of capture changes depending upon the number of times the individual is captured earlier. The probability may go up (trap attraction) or down (trap shyness).


datasets

Collection of datasets as prepared by Profs. A.P. Gore, S.A. Paranjape, and M.B. Kulkarni of Department of Statistics, Poona University, India. With their permission, first letter of their names forms the name of this package, the package has been built by me and made available for the benefit of R users. This collection requires a rich class of models and can be a very useful building block for a beginner.
