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. 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.

HLM还提供了估计分层广义线性模型的自适应Gauss-Hermite Quadrature (AGH)和
高阶拉普拉斯Laplace近似大似然法。AGH的方法已经被是有效的,尤其当集群规模小,方差分量大的时候。高阶Laplace方法需要较大的集群大学,但允许任意数量的随机效应(当集群较大时非常重要)。
HLM新版本的输出,为统计模型提供优雅的符号,包括视觉上有吸引力的表格、用户可以剪切和复制输出内容到结果中。
HLM fits models to outcome variables that generate a linear model with explanatory variables that account for variations at each level, utilizing variables specified at each level. HLM not only estimates model coefficients at each level, but it also predicts the random effects associated with each sampling unit at every level. While commonly used in education research due to the prevalence of hierarchical structures in data from this field, it is suitable for use with data from any research field that have a hierarchical structure. This includes longitudinal analysis, in which an individual's repeated measurements can be nested within the individuals being studied.
The final output given is the deviance statistic for this model, together with the degrees of freedom.
This information may be used to compare the fit of two models, as can be seen in the section on
hypothesis testing.
In the next example on this page modification of this model and the testing of hypotheses
concerning both fixed effects and the homogeneity of the level-1 variance will be considered.
Note that HLM will also save the input information into another file called
CREATMDM.MDMT when the MDM is created.
Click the Make MDM button. A screen displaying the prompts and responses for
MDM creation will appear.
