Phase Dispersion Minimization (PDM) is a statistical method used primarily in the analysis of time series data, especially in the field of astrophysics for studying periodic signals, such as those coming from variable stars, pulsars, or exoplanets. The main goal of PDM is to determine the period of a signal by minimizing the dispersion of the phased data.
