Walker, Moshe Ben-Akiva, and Denis Bolduc, "Identification of Parameters in Normal Error Component Logit-Mixture (NECLM) Models", Journal of Applied Econometrics, Vol. 22, No. 6, 2007, pp. 1095-1125. There are two datasets used in this paper: (1) A synthetic dataset (Figure 1, Table 1) (2) A telecommunications dataset (Table 3 and Table 4) The estimations were performed using Biogeme (http://transp-or.epfl.ch/page63023.html) and Kenneth Train's gauss code (http://elsa.berkeley.edu/Software/abstracts/train1006mxlmsl.html). The file WBB-synthetic.zip contains data contains data files for the synthetic dataset in ASCII (DOS) format, plus all estimation input and output files. The file WBB-telephone.zip contains data files for the telecommunications dataset in ASCII (DOS) format, plus all estimation input and output files. The file WBB-file-details.pdf describes each dataset, datafile, and the estimation input and output files.
