mmmec: EC data on UV radiation exposure & malignant melanoma.

Description

EC data on UV radiation exposure & malignant melanoma, consisting of 354 counties across 79 regions across 9 nations.

Usage

mmmec

Format

A data frame with 354 observations on the following variables:

nation

Nation ID: a factor with levels corresponding to each country.

region

Region (within-nation) ID.

county

County (within-region) ID.

obs

Number of male deaths due to malignant melanoma between 1971 and 1980.

exp

Expected number of deaths - proportional to county population.

cons

Constant (=1).

uvbi

County-level measurement of UV B radiation, centered on the mean.

Details

The mmmec dataset is one of the sample datasets provided with the multilevel-modelling software package MLwiN (Rasbash et al., 2009). Further information can be found in Langford et al. (1998) and Browne (2012).

 D = "Poisson", estoptions = list(EstM = 1), data = mmmec))
