This paper explores the potential of a special instance of the Combination of Random Utility Models (CoRUM; Papola, 2016), termed Combination of Nested Logit (CoNL), as kernel model in conjunction with several types of mixing distributions of tastes (parametric, nonparametric, semiparametric). Various model formulations are illustrated with their mathematical properties, and several alternative kernel models are identified for comparison. An estimation exercise is presented on a real mode choice dataset from a stated preference survey on the intercity corridor between Naples and Milan in Italy. Results, in terms of both in-sample and out-of-sample goodness-of-fit on a 10-fold cross-validation show that models with the proposed CoNL kernel outperform contrasted models.
