Abstract

Modelling rainfall presents difficulties: one is that rainfall is both continuous and discrete. The discrete component corresponds to exactly zero rainfall.
Some researchers circumvent this by using two models - one for determining the
presence and absence of rainfall, another for the rainfall amount. Here, we use
power-variance (Tweedie) generalized linear models, which can explictly model
continuous data with exact zeros. We demonstrate there is a basis for using these
models; that the parameters, in some cases, lend themselves to a useful interpretation; and show the models fit the data well using monthly rainfall data from
Charleville. We then model Australian annual rainfall, and develop a contour
map for the power-variance model index parameter.

KeywordsTweedie model, rainfall, generalized linear model, power-variance models.
