Confidence in Phase Definition for Periodicity in Genes Expression Time Series

The Bootstrap Percentile confidence interval principle.
Schematic of the bootstrap process. We want to estimate a confidence interval for the phase θ(χ). R training sets, χ1*, …, χR* each of size n are generated using an appropriate resampling mechanism. The quantity of interest θ(χ) is computed from each bootstrap training set, and the values are used to construct a confidence interval for the quantity θ(χ).
