Malaria prevalence in children in Gambia. The data are constructed from the gambia dataframe in the geoR package (Diggle and Ribeiro, 2007) by village aggregation.

cases | number of sampled children with malaria in each village. |
size | number of sampled children in each village. |
age | mean age of the sampled children in each village. |
netuse | frequency of sampled children who regularly sleep under a bed-net in each village. |
