A Bayesian Network (BN) model of female rib cage size and quantified categories of body habitus as presented in the article Development of populational female thorax sizes and body habitus categories using computed tomography (CT) images - ScienceDirect. This is a retrospective analysis of 347 female CT chest axial scans was retrieved from an open access database to establish female rib cage sizes. The model structure specification was determined by following the novel sampling-subject-oriented approach (10.31235/osf.io/gqud3). The classification into three body types was derived from a Multiple Correspondence Analysis performed in R, and the resulting classifications were used as one of the variables in the development of the BN model.
