Hubert-Kehagias Aggregation¶
Summary¶
Perform a basic Hubert test and aggregate homogeneous segments in an AGO field.
Tags:hydrography, hubert, statistics, aggregation, ago, dgo, segmentation
Usage¶
Aggregate disaggregated objects with respect to a given metric, using the Hubert-Kehagias segmentation procedure. A ID_AGO field is created to identify the homogeneous segments. The Hubert Test is an univariate statistical test based on the standard deviation, enabling to identify locations of breaks into a set of numerical data. The output set of data is modeled as succession of straight and constant lines (or “segments”). (Roux et al., 2014)1
