Time-limited, fully functional licenses for students enrolled in courses or workshops are available free of charge, provided that the instructor maintains a paid and active SSI Live™ Standard subscription to the program in question. Just let us know the start and end dates of your classes, and the names and email addresses of the enrolled students so we can set up these individual licenses. Once the licenses are ready, we will let you know, and then you may inform your students that the licenses are available for their use. This option is available for HLM, LISREL, and SuperMix. For more information, please contact us at email@example.com.
HLM provides statistical tools for comprehensive hierarchical data modeling. A recent addition to this popular program is the option to estimate an HLM from incomplete data, using a completely automated approach that generates and analyses multiply imputed data sets from incomplete data.
LISREL provides tools for structural equation modeling, data manipulations and basic statistical analyses, hierarchical and non-linear modeling, generalized linear modeling, and generalized linear modeling for multilevel data.
SuperMix is an application for comprehensive mixed-effect modeling and combines the functionality of four mixed-effects programs, MIXREG, MIXOR, MIXNO, and MIXPREG, developed by Donald Hedeker and Robert Gibbons into a single application to provide estimates for mixed-effects regression models.
PARSCALE implements Item Response Theory (IRT) measurement methods for binary, multiple-category and rating-scale items. The flexibility and the wealth of information provided by this program have kept it in regular use by researchers around the world.
BILOG-MG is an extension of BILOG that is designed for the efficient analysis of binary items, including multiple-choice or short-answer items scored right, wrong, omitted, or not-presented. BILOG-MG is capable of large-scale production applications with unlimited numbers of items or respondents.
Auxal performs both structural and nonstructural auxological analysis of human growth in standing height or recumbent length.
Currently we offer no native Mac version of any of our programs currently available. However, if you have a dual-boot set-up or a Windows emulator, any of our programs should run without issues. Note that we can only provide support for using the software and are unable to provide guidance on setting up a Mac to allow for a program to be usable. Parallels Desktop is the most frequently used of the emulators. VirtualBox is a free alternative from Oracle, but it can be very slow compared to Parallels.
