plasma.silicon

A study was conducted to measure the plasma silicon level in blood within 30 women 
who have been taken a silicone implants surgery. Plasma silicon levels (microg per gram dry weight) 
were taken prior to surgical placement of the implants. A post-surgery washout period was allowed, 
and the plasma silicon levels were retaken.

datasets

Provides functionality of a statistical testing implementation whether a dataset comes from a symmetric distribution when the center of symmetry is unknown, including Wilcoxon test and sign test procedure. In addition, sample size determination for both tests is provided. The Wilcoxon test procedure is described in Vexler et al. (2023) <https://www.sciencedirect.com/science/article/abs/pii/S0167947323000579>, and the sign test is outlined in Gastwirth (1971) <https://www.jstor.org/stable/2284233>.
