COWSDATA


A project on crossbreeding of cows was conducted at multiple centers. A cow when inseminated during heat may or may not conceive.  Factors likely to affect success are semen used (fresh or frozen), hormonal status of cow, etc. Cows were brought to the centers when they were found to be in the "heat" state.  Time lag between onset of heat and insemination was noted as also success or failure of insemination. Veterinary practitioners believe that maximum "success" is observable if the insemination is practiced within 24-30 hours from onset of heat. 


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.
