precisely: Estimate Sample Size Based on Precision Rather than Power

Estimate sample size based on precision rather than power. 'precisely' is a study planning tool to calculate sample size based on precision. Power calculations are focused on whether or not an estimate will be statistically significant; calculations of precision are based on the same principles as power calculation but turn the focus to the width of the confidence interval. 'precisely' is based on the work of Rothman and Greenland (2018) <doi: 10.1097/EDE.0000000000000876>.
