sample_s

Estimates the required sample size so that the confidence interval width
for SCR does not exceed a specified limit.

Sample size and confidence interval calculations in reversible catalytic models, with applications in malaria research. Further details can be found in the paper by Sepúlveda and Drakeley (2015, <doi:10.1186/s12936-015-0661-z>).
