摘要
用生存分析方法研究具有删失数据的旅游随访问题，对各时间区间继续旅游概率由Ａ、Ｂ、Ｃ３ 种统计量估计，给出一种适合旅游问题的生存分析参数模型，其参数估计有一定的实际意义。
The problem of the following\|up data of tourism is studied by using the statistics A,B,C.They are used to estimate the probability of cut\|out data for every interval and every district.A model for survival analys is given to fit for interval survival probability and to estimate the parameter.An example is provided as an application in tourism.
