Extended Data Fig. 3: Change point analysis of the CHB14-2 K/Zr record.
From: Pleistocene climate variability in eastern Africa influenced hominin evolution

Change points in the statistical measures in the K/Zr record from CHB cores were determined to structure the long CHB-14-2 K/Zr record using the MATLAB-based function findchangepts contained in the MATLAB Signal Processing Toolbox. We run findchangepts for the arithmetic mean (Supplementary Fig. 3a), standard deviation (Supplementary Fig. 3b) and trend (Supplementary Fig. 3c) for a maximum of five important changes. All change points were applied to the CHB14-2 K/Zr time series, dividing the record into 13 episodes.
