This article introduces a class of models for multidimensional network data, where different levels of heterogeneity within and between networks can be considered. The proposed framework is developed in the family of latent space models, and it aims to distinguish symmetric relations between the nodes and node‐specific features. Model parameters are estimated via a Markov Chain Monte Carlo algorithm. Simulated data and an application to a real example, on fruits import/export data, are used to illustrate and comment on the performance of the proposed models.||Funding Details:||Science Foundation Ireland||Funding Details:||Insight Research Centre||Type of material:||Journal Article||Publisher:||Wiley||Journal:||Statistica Neerlandica||Volume:||74||Issue:||3||Start page:||324||End page:||341||Copyright (published version):||2020 the Authors, Statistica Neerlandica, VVS||Keywords:||Latent space models; Markov chain Monte Carlo; Multiplex||DOI:||10.1111/stan.12209||Language:||en||Status of Item:||Peer reviewed||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by-nc-nd/3.0/ie/|
