STREAMS (Structural Equation Modeling Made Simple) has been designed with two main purposes in mind:
These aims are reached in the following ways:
STREAMS currently supports the following model fitting programs::
EQS (Structural Equation Systems) has been developed by Peter Bentler at the Psychology Department at UCLA and is distributed by Multivariate Software Ltd.. The first versions of the system were developed in the early 1980s, and offered an alternative to LISREL's matrix based method of model specifion, namely model specification through specification of equations. Later versions of EQS also offer a path diagram interface, through which the user draws the model as a diagram, which by the program is then translated into equations. EQS also offers a wide variety of advanced estimation techniques, and offers, in particular, techniques useful for dealing with non-normal data,. and for computing robust test-statistics. The program also computes a wide range of goodness-of-fit measures, and other useful statistics.
STREAMS 3.0 supports EQS 6.1 .
LISREL (LInear Structural RELations) has been developed by Karl Jöreskog and Dag Sörbom at the Department of Statistics, Uppsala University in Sweden and is distributed by Scientific Software Inc.. The first versions of LISREL appeared in the early 1970s and the contributions made by Jöreskog and Sörbom are regarded as the ground-breaking work in structural equation modeling. During the three decades that LISREL has existed, numerous improvements and extensions have been made. Thus, in addition to the somewhat complicated but extremely powerful matrix based language of the original program there is now also a simplified, English-like, language (SIMPLIS) as well as a path diagram interface. The program offers a wide range of estimation methods and goodness-of-fit statistics, and it usually estimates the models very efficiently.
STREAMS 3.0 supports LISREL 8.50 to LISREL 8.70 .
Mplus has been developed by Linda and Bengt Muthén at Muthén and Muthén, and the program implements, among other things, advanced SEM procedures developed by Bengt Muthén in his research and the Department of Education and Information Studies at UCLA.. This is a newcomer among SEM programs, being released in 1998, but it builds upon Muthéns LISCOMP program from 1987. Mplus provides all the standard SEM techniques, and it also offers a rich variety of advanced techniques for dealing with more complex data and models, such as non-normal data, ordinal data, two-level data, missing data, weighted data, multiple cohort data. The Mplus program also offers an integration between latent class analysis and ordinary latant variable modeling, thereby extending the modeling techniques into second-generation SEM.
STREAMS 3.0 supports Mplus 1 to Mplus 3.
STREAMS also supports Amos 4, which program is, however, no longer distributed.
