Discrete choice with an oddball alternative

摘要: Abstract A discrete choice model is presented that explicitly recognizes differences in the error structure associated with a single “oddball” alternative within set has properties not common to other alternatives. The purportedly resolves questions related use of alternative-specific variables transportation models capture effects attributes unique travel alternative, such as “schedule frequency” case modal between personal auto and public transit. model, which shares general multinomial logit, shown be modification logit subchoice by terms involving exponential integral. yield different results from those produced an equivalent specification. Comparisons probit nested formulations are also made.
