cloudseed: Cloud Seeding

In gpk: 100 Data Sets for Statistics Education

Description

4. It is now believed that we can induce rainfall by seeding clouds i.e. releasing certain chemicals (silver iodide) in clouds. Of course there can be doubts such as whether there is indeed a net increment in rainfall or just a re-distribution over a certain territory etc. Analysis of relevant data can therefore be of considerable interest. In this experiment days for seeding were selected randomly out of a set of 52 days suitable for seeding.

Usage
