Results for simulated data: 2 clusters with 7 categorical variables having interaction terms up to second order. In all interaction graphs, the light-blue circles represent the main effects, the blue lines represent 1st-order pairs and the reddish triangular lines indicate 2nd-order triplet interactions. In each case, the size of the circle or the width of the lines indicates the estimated significance of the main effect or the higher-order interaction: i.e. For example on the right cluster, more than 90% of the posterior samples for variable 2 have a positive sign. Based on the results of the inference process, we observe that all the key features have been correctly identified.
