## Brief description

This web application is an implementation of sample size calculation methods for binomial test in JavaScript.

Threshold proportion ($p_0$) correspond to the null hypothesis.

Expected proportion ($p$) correspond to the alternative hypothesis.

Normal approximation: this application use the score-type standard error (i.e., standard error under $H_0$).

Exact test of a binomal porportion: This method can be computationally intensive. Please be careful.
