DISCRIMINANT AND LOGIT ANALYSIS - A COMPARISON OF METHODS

DISKRIMINANT-OCH LOGITANALYS--EN METODJAEMFOERELSE

The aim of this study was to compare empirically logit analysis with discriminant analysis as methods of analysis of modal choice. The comparison was made by applying both methods to the same data and thus studying the accuracy of the methods in explaining the modal choice. The two models are of the same type, but are based on different premises and conditions. Both models express the probability of a certain individual choosing the car as a transport mode as a function of variables explaining modal choice. The study shows that the same explanation variables gave the most accurate result for both methods and that the logit model gave a slightly higher degree of explanation. The time values obtained were almost equal. Regarding forecasting, discriminant analysis proved the most accurate, while the logit model expressed the proportion of car passengers and classified the individuals more accurately. /TRRL/
