Fish


Brook trout and cut-throat tout are two species of stream fish. If they compete with each other then high density of one may suggest absence of the other. If they are symbiotic, high density of one may promote the other. These data are from streams. Typical mountain streams are about 2.5m wide. (Kilograms per hectare is a conventional density measurement used in lakes) 
Can we predict presence/absence of Yellowstone Cutthroat trout as a function of density (kg/ha) of Brook trout?


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.
