Samenvatting
In stated choice experiments concerning travel behaviour the number of observations is often increased by making repeated observations on each participant. In estimation, this can cause problems with the error structure. In this paper a solution known from panel data literature is presented and applied to demonstrate that complex estimations are feasible and investigate the seriousness of the problem. Applying the procedure on stated choice observations in trip decisions, it is concluded that estimations did not deviate significantly. (Author/publisher).
