Posterior analysis of random taste coefficients in air travel behaviour modelling

Hess, Stephane - In: Journal of Air Transport Management 13 (2007) 4, pp. 203-212

Increasing use is being made of random coefficients structures, such as mixed logit, in the analysis of air travel choice behaviour. These models have the advantage of being able to retrieve random variations in sensitivities across travellers. An important issue, however, arises in the...

Can scale and coefficient heterogeneity be separated in random coefficients models?

Hess, Stephane; Rose, John - In: Transportation 39 (2012) 6, pp. 1225-1239

There is growing interest in the notion that a significant component of the heterogeneity retrieved in random … coefficients models may actually relate to variations in absolute sensitivities, a phenomenon referred to as scale heterogeneity …. As a result, a number of authors have tried to explicitly model such scale heterogeneity, which is shared across …

Conditional parameter estimates from mixed logit models: Distributional assumptions and a free software tool

Hess, Stephane - In: Journal of Choice Modelling 3 (2010) 2, pp. 134-152

A number of authors have discussed the possible advantages of conditioning parameter distributions on observed choices when working with Mixed Multinomial Logit models. However, the number of applications is still relatively small, partly due to a limited implementation in available software. To...
