Cloud Seeding in Tasmania

Keywords: regression, permutation tests.

Description

These data were collected in a cloud-seeding experiment in Tasmania between mid-1964 and January 1971. The rainfalls are period rainfalls in inches.

Seeded	-	S = seeded, U = unseeded
Season	-	Autumn, Winter, Spring Summer
TE	-	rainfall in east target area
TW	-	rainfall in west target area

The data was recovered from the Statlib datasets directory.

Analysis

The analysis of Miller et al (1979) used regression techniques and permutation tests.

The rainfalls are definitely non-normal. It is interesting to estimate a transformation or distribution for the measurements.
