  1. Statistical model for variation among historical periods in the annual number of primary outbreaks recorded at the national scale in Zimbabwe. The 1980–2000 period characterized by the prosperity following independence is considered as the reference period for pairwise comparisons among periods. The p-values associated with comparisons of each period with the reference period are obtained though.
