| − | With the exception of "Maintain recovery info", all preference settings are stored with your model. Internally, each of these preferences is stored in an Analytica [[Ana:System Variables| system variable]]. Only settings that have changed from the default value are actually stored with the model.
| |
| − | | |
| − | When you use "Add Module..." or "Add Library..." to add a file to your existing model, preference settings are imported from that file ONLY IF the file is a model file. If it is a linked module or linked library, then preferences are not stored with the file. Generally, if you plan to re-use a "component" in many models, you will usually store it as a linked module or linked library (set the Class attribute to one of these), and not as a model, unless of course you do want to import system variables and preferences when that model is included.

| − | * For a variable defined as a probability distribution or sequence, it opens the definition in the Object finder when the preference is set to "Diagram attribute panel".
| |
| − | * For a user-defined Functions, it always opens an Object window. This is convenient since you usually want to work with the parameter and definition fields simultaneously. (New to 4.0)

| |
| − | | |
| − | When checked, Analytica logs all changes since the last model save to a recovery file. If Analytica is terminated unexpectedly, from a crash, power outage, etc., those changes can be recovered so that your hard work is not lost.
| |
| − | | |
| − | Even when this is checked, it is still recommended that you save often.
| |
| − | | |
| − | If a crash occurs, a recovery dialog will display the next time you start Analytica, or the next time you attempt to load the model that was being edited.
| |
| − | | |
| − | If your model contains extremely large edit tables, this feature may slow down the editing of those tables, and disk space is consumed from the change log.
| |
| − | | |
| − | Unlike the other preference settings, this setting is stored as a user setting, and is not stored with the model.

| − | In general, filling in descriptions of all variables and modules will dramatical increase transparency of your model. Use of this feature can help identify variables where descriptions have not yet been filled in.

| − | Like Excel, Analytica represents dates using an integer, which signifies the number of days that have passed since a certain date origin. When this preference is NOT checked, Analytica uses a date origin of Jan 1, 1904, so that, for example, the value 38000 represents 38,000 days after 1 Jan 1904, or 15 Jan 2008. When the preference is checked, Analytica uses the origin 1 Jan 1900, so that 38,000 denotes 16 Jan 2004.
| |
| − | | |
| − | Analytica 3.x and earlier used the origin 1 Jan 1904. Excel on Macintosh, as well as most other Macintosh programs also use this origin. However, Excel on Windows uses 1 Jan 1900. If you copy/paste dates as integers between Excel and Analytica, setting this preference helps to maintain consistency. However, if you are using pre-existing Analytica models containing dates, you may need to keep this preference off.
