Document Summary

Aggregation was defined as the estimated variance to mean ratio: widely observed aggregation in parasite burden arises from, materials and methods heterogeneities in the host populations or in infection pressures, these heterogeneities are generated by changes in the climate over time of space, genetic differences between hosts in terms of parasite induced host mortality, heterogeneity in infection levels, or even variation in the number of infectious stages encountered per infection event. , aim of the study was stated. Perhaps that is related to the fact that this is a review paper, and they are just looking at data that has already been collected to get a sense of the general trends: started off with an explanation of the statistical analysis methods that were used in the study, researchers state that the degree of aggregation can"t really be found, but they use a value defined as k as an estimate for the degree of estimation, used an unpublished paper for this.
