General

What is GLM?

GLM stands for the "General Linear Model". This is the basic statistical model which contains ANOVA, regression analysis, and contingency table ("chi square") analyses and their multutivariate counterparts.

What is unique about UniMult compared to other statistical packages?

It is designed and programed from the first to last line of code as a GLM processor. The advantages are:

        1. The program analyses any combination of variables without needing being restricted to any particular ANOVA or regression design so you select the variables needed, not whether it fits one jargon or another. As the jargon is minimal, it is easy to learn.
        2. As there is no need to select a method of analysis -- such as ANOVA --. you simply select your variables and the program does the correct analysis, labeling your output with the appropriate title. Multiple analyses are quickly run.
        3. Simple and easy to run is matched with report / article / presentation quality tables and figures.

How does UniMult know whether it is an ANOVA or regression?

By noting the level of measurement of the variables (see Guide), it gives the appropriate label for your output.

Why is my Mac OS X 10.8 (and newer) preventing me from starting UniMult because of unidentified developer?

The new security features in Mac OS X 10.8 (Mountain Lion) prevent users from launching UniMult using the standard system security settings. UniMult has attained trusted certificates that insure that UniMult does not contain malware and other harmful software. However, Apple's change now only recognize software coming from Apple's App Store. A system wide setting needs to be changed in the preferences, and this has security implications. We are looking into code signing to resolve this issue.

To use UniMult, you must make the following changes:

          1. Go to the System Preferences
          2. Select Security & Privacy
          3. Click the lock to make changes and authorize as an admin (if necessary)
          4. Select "Allow applications downloaded from: Anywhere"

You should now be able to launch UniMult. You should be extra vigilant about the source of any downloaded applications while your computer is in this state.

If you stop needing to use UniMult, we recommend you reset your settings:

          1. Select "Allow applications downloaded from: Mac App Store and identified developers"

Why can't I use Chrome with Java 7 on my Mac?

Chrome is a 32-bit browser. A 64-bit browser (Safari or Firefox, for example) is required to run Java 7 on Mac OS X. 32-bit browsers such as Chrome do not support Java 7 on the Mac platform.


Why am I receiving an error “File open by another program” when saving my results?
