KevinRobache/PDF_Quotient_Code: PDF Quotient Code

This code estimates the quotient of probability density functions (PDF) between two time series, following the approach originally proposed by Xu et al. (2007). It is associated with the study of Robache & Schmitt (2025), published in Biogeosciences (Copernicus journal). If you use this code, please cite the following references: Xu, H., Ouellette, N.
