Poisson distribution in plausibility report

[Blessing MureverwiParticipant]

The STP appears to suggest that the poisson distribution applies to cluster sampling, where it looks at heterogeneity, or the presence of “malnutrition pockets” . How does it apply to an exhaustive survey or a simple/systematic random survey? Does it apply in the same way? I recently came across a data set where the plausibility report gives a “problematic” score for poisson distribution.

You are correct that the Poisson distribution applies to cluster sampling and examines level of heterogeneity or the presence of pockets of malnutrition. The Poisson distribution does NOT apply to an exhaustive survey or simple/systematic random surveys because there are not any clusters to compare levels of heterogeneity. Please disregard the Poisson distribution analysis in the plausibility report if a cluster survey design was not used.

Fantastic.Thank you.
