ALOGIT is controlled by the program, which acts as an interface between the user, Windows and the ALOGIT program itself.
The ’s main role is to edit ALOGIT control files and to run ALOGIT. In these functions it offers all the standard Windows operations with cut-and-paste editing and its own Help system. The facilitates working with multiple models in a project. Additionally, it has further functions...
- the capability to make Jack-knife runs to explore the impact of model specification errors;
- a coefficient comparison viewer, with a function allowing the user to examine the difference in coefficient values between models; the can also calculate correct errors in coefficient differences, allowing a statistical test of whether coefficients are different, and errors in coefficient ratios, so that error in (for example) willingness to pay can be calculated
- a user friendly Windows based batch file program which can be activated from the , allowing the user to perform multiple ALOGIT runs;
- the integration of a reporting system, allowing the presentation of model scenario output using tables and graphs.
The also controls the editing of ALOGIT INI files, which control the way in which ALOGIT interacts with the PC: the use of RAM, production of screen reports and the deletion of scratch files, for instance.
All of these functions are controlled by ALOGIT’s intuitive control file, with
组合logit模型只包含在ALOGIT EC中。
ALOGIT 执行以下四个关键功能。
数据输入
可以使用显示偏好或陈述偏好,分类数据或综合数据;可以使用选择、排名或比例分割数据。
输入数据可以自由操作和转换,以允许用户自由地找到所需的行为解释。对输入数据进行广泛的测试,以揭示建模问题;简单的控件,在完全成熟时需要访问。
接受不同格式的多个数据集,连续或使用命名(key)变量链接;支持一些二进制矩阵格式。
模型估计
使用极大似然估计同时估计所有系数(即完整信息估计)。
模型可以是二项式、多项式或树(嵌套的)logit模型,具有无限的分支和层次;或者,混合的logit或误差成分分析,包括不同的分布(包括指数,如对数正态)和相关误差项。
非线性效用函数允许正确地包含吸引变量。
综合备选方案可以表示为已选。
系数估计、标准误差、正确计算的弹性、消费者剩余措施及若干细节检验都是标准的,信息量大、标签清新、输出清晰,适合立即放入报告中。
ALOGIT 中的函数可以用来在不同的模型变量之间进行比较。
初始线性估计的选项减少了复杂模型的运行时间。
ALOGIT不会限制问题的大小。
problem sizes are not limited by ALOGIT.
