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.
mixed logit models, implemented using the flexible ‘error components’ specification, which works with either linear or the exponentiated form, which allows, for instance log-normal disturbances in the coefficients.
intuitive specification of tree logit models using $NEST commands.
所有这些功能都是由ALOGIT的直观控制文件来控制的
一种非常灵活的命令语言,包括命名变量、层次模型直观的定义结构、命名为布尔运算符(TRUE、FALSE、利用率等)。
包括使用命令行或系数的外部文件选项,简化模型(估计)管理。
备选方案的数组定义、系统数据项和变量。
随机数产生器(具有特定的概率的多项式变量的一致、正常、逻辑分布或赋值)。
‘if ... THEN ... ELSE... END’ and ‘DO ... END’语法,来简化数据转换。
使用$NEST命令的tree logit模型的直观说明。
系统要求
ALOGIT支持Windows或以上的操作系统,也支持旧的操作系统XP, 2000, NT, 98和95。
- the user can specify detailed scenarios which incorporate a series of changes in the variables influencing choice, and ALOGIT can predict, display and analyse the consequent changes in behaviour;
