摘要：
Many data are investigated by questionnaire. However, these data using questionnaire are discrete and more continuous data are needed. Therefore, a method of obtaining continuous data from discrete survey data based on non-linear least square and corresponding algorithm are proposed in this paper. Moreover, the survey data of travelers' income in Beijing-Shanghai Corridor are studied, and experimental results indicate that the method proposed is effective. (c) 2012 Published by Elsevier B.V.
