Sample size calculation should be done in R.
Task:

• figure out the method used in ENA for cluster sampling (http://www.nutrisurvey.de/ena/ena.html)).
• Investigate what the survey package can do for us.

Random sampling seems to just be random number generation.

For the CFR estimates once could use simple binomial proportion CIs or maybe use the survey package to get better CIs for the different strata/cluster. Any input here is welcome.

I also see negative CIs which suggets these are not binomial proportions (should be between 0 and 1).

Is is something we want to do? Together with sample size calculation and the sampling in R, maybe we can also generate other supporting material for operations? Just an idea

As in #1 the Emergency Nutrition Assessment (ENA) for Standardized Monitoring of Relief and Transition (SMART) software is used.

• Replicate method in R
• Check if survey package fits in here
• check other materials regarding sample size calculation from WHO

I see one study using the OpenEpiMenu software.

• Checkout the method of the software and see if/how it can be replicated in R

It seems maps are useful in all surveys, however not always used. I suppose some general code snippets for map generation might be useful and should be part of the report templates.

Any thoughts?

Where do the population estimates for clusters / whoe area come from? Is this manually extracted from different source or are there external data sources you would often use?
