Abstract : Automatic segmentation of data into coherent subsets is important in applications as varied as signal processing, bioinformatics and pharmacology. Under this general framework, we investigate the problem of data-driven reconstruction of an unknown, piecewise-constant density function and propose two methods to solve it; the first is directly inspired by the segmentation approach, whereas the second uses a maximum likelihood approach. Motivated by a problem in pharmacometrics, we then introduce a segmentation algorithm which fits into the same general framework and is used for automatically binning data for model assessment purposes.

Keywords : Histogram Segmentation Signal Piecewise-constant density function Maximum likelihood Pharmacology Visual Predictive Check Dynamic programming Histogram.
