Online Manual

To open the program, simply double-click on the AM software icon. The AM program has a main menu bar and three windows:

The Variable List, which appears on the left and side of the screen, and which you can use to view and manage the variables in your data file.
The Run Queue, which appears in the bottom right quadrant. Statistical models that you are preparing appear here until it is their turn to run.
The Completed Run Queue, which holds statistical runs once they are complete. Most statistical models allow you to conduct post-hoc analysis by right clicking icons in the completed run queue.

The program looks like this when it first opens:

starting the program

The first step to using the program is getting data into the program. Right now, there are six ways to get data in:

Import an ASCII data set
Open an existing data set.
Extract data from an existing AM data file.
General Import from one of over 100 different file formats, including SAS and SPSS.
Import from SPSS.
Import from a SAS Transport file, which currently is not an efficient way to read data in, and is better accomplished using the general import/export facility.

Once the dataset is opened, you can recode your variables using the facilities described under "Manipulating Data," many of which appear on the Variable Menu.

When you are ready, you can select the statistical models you'd like to run from the "Statistics" option on the main menu bar. For help on the statistics, highlight the statistical procedure in which you are interested, and press F1.
