A
student version of SuperMix 1 for Windows can be downloaded from this page.
Please print this page before downloading the student edition, as the restrictions and other useful information concerning the program are given here. Also note that no technical support is provided for the student edition and that no serial number is required during installation.
The student edition of
SuperMix 1 for Windows is available as a single, self-extracting executable
SuperMixStudentSetup.exe.
- Download this
file to a temporary folder (for example C:\tempfiles).
- Run SuperMixStudentSetup.exe
from the Start Menu or Program Manager.
- Default installation
will be to a new folder "C:\Program Files\SuperMixEn Student".
You may change the name and location of this folder. After
successful installation the downloaded file SuperMixStudentSetup.exe
may be deleted.
The student edition
contains the following:
- All the examples distributed with the full SuperMix 1 for Windows version. Most of these examples may be run with the student edition (see restrictions below).
- An on-line helpfile,
as provided for the full version too. The helpfile includes
most of the new SuperMix 1 for Windows manual and a complete tutorial showing
the use of SuperMix.
By default, SuperMix examples are copied to the folder C:\SuperMixEn Student Examples\
during the installation process. The choice of folder is based on the following
MicroSoft guidelines for the installation of applications on Windows Vista
platforms:
- The application must reside in a protected location in the file system.
\Program Files\ and \Windows\System32\ are currently the two allowable
protected locations.
- Applications should not attempt to write to locations, such as the following:
* C:\Windows
* C:\Windows\System32
* Program Files\{application}
Considerations: Vista users copying examples to Program Files folder
If the examples are copied to the Program Files folder, the application believes
it was able to successfully read and write directly to Program Files. The
transparency of file virtualization with Vista enables applications to perceive
that they are writing and reading from the protected resource, when in
fact they are accessing the virtualized version.
For example, a user is running a computer that is shared with others. This user
attempts to save an SuperMix output file under the Program Files\SuperMix\Examples directory: \Program Files\Examples\SchoolsData.txt. Although
Program Files\SuperMix\Examples\ is protected, the file will be saved successfully
from the application's point-of-view because of Windows Vista file virtualization.
To achieve this, the file write is redirected to
Users\Username\AppData\Virtual Store\Program Files\Examples\SchoolsData.txt.
For the user to discover his virtualized files, he must navigate to the virtual
store with the Compatibility files button on the Explorer toolbar. The files
that a particular user updates and saves will remain independent of the other
virtualized files on the computer.
The student edition
can run all the analyses the full version can in terms of
models selected, statistical options and output. Restrictions
are, however, placed on the data used and the size of the
model selected. The following restrictions apply in this edition:
- Number of variables:
The Student Version is limited to 15 Variables, where number of variables equals
the number of Dependent + the number of Predictors + the number of Random 2 and
3 Effects.
- Number of cases:
The Student Version is limited to 10,000 cases, that is, level-1 units.
- Files can not be imported from statistical software packages such as SPSS, SAS and STATA.
- Technical support:
SSI does not offer technical support for student versions of their programs.
When these limitations
are exceeded, an appropriate error message will automatically
be displayed.
This is accomplished by selecting the "File, Import Data File..." option.
Note that row 1 of the spreadsheet (Student Version only) contains the variable labels.
To rename the column headers to reflect the variables in each column, first left-click
on the row 1 tab to select the complete row and then right-click and select the "Create Headers from Row" option from the pop-up menu.
The spreadsheet headers will now correspond to the names shown in the first row of the
spreadsheet. This row is no longer needed, and is deleted by right-clicking anywhere on
row 1 and then selecting the "Delete Row" option from the pop-up menu. Use the "File,Save"
option when done.
- Default missing value for student version of SuperMix spread sheet is -999999. When importing a data file, the dots or empty cells will be replaced by default missing values.
- Only one missing value in each SS3 file will be recognized.
For more information
on how to set up these models and how to interpret the output,
please see the Help file that comes with the program. Also (partially) available on this website.
