In principle, there are no limits to problem sizes. Highly specialised fast calculation routines are provided, for example to calculate exact first and second derivatives of the likelihood function. The concept of ALOGIT is to provide highly tailored, and therefore very efficient, optimisation for a restricted range of model specifications, however including several important generalisations (including, for example, size variables). from mobile phone records), or any combination of these. In this context, observations could be reported behaviour (e.g., in an interview), stated choices, ‘big data’ (e.g. # ALOGIT # Brief DescriptionĪLOGIT is software for the statistical estimation of the coefficients of multinomial logit, tree-nested logit and simple mixed logit models, using the criterion of maximum likelihood to obtain coefficients that best explain observed behaviour. Web site/contact information is provided for each software. It should be noted that some of these software packages can be used for other types of model estimation besides travel models, and some packages that are designed more generally for statistical model estimation are used for travel model estimation. The information provided here is from software developers and publicly available sources. This page provides brief summaries of software used in statistical estimation of travel models.
