Linear fitting models about multi-group data are studied in this paper.Firstly,based on four different methods,four kinds of fitting models are given.Then the prominent differences among the models are analyzed by the ttest method.Our results provide a rational scheme or way for choosing models of practical questions.Finally,our results are used to estimate the number of passengers in highroad transportation.
