%description
Calculates sample size for various scenarios, such as sample size to
estimate population proportion with stated absolute or relative precision,
testing a single proportion with a reference value, to estimate the
population mean with stated absolute or relative precision, testing single
mean with a reference value and sample size for comparing two unpaired or
independent means, comparing two paired means, the sample size For case
control studies, estimating the odds ratio with stated precision, testing
the odds ratio with a reference value, estimating relative risk with
stated precision, testing relative risk with a reference value, testing a
correlation coefficient with a specified value, etc.
