Euphorbiaceae


For various reasons it is of interest to estimate volume of a tree. Obviously direct measurement is quite difficult. The next best thing is to assume that the tree has a conical shape. Even with this assumption we need to measure height and radius at the base for estimating volume. Measurement of height can be cumbersome. However, measurement of girth is easy at about one meter height.  Hence the simplest method is to use some relationship between girth and height and estimate height from girth. 


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.
