hierarchical linear models
type: Concept
broader: multilevel analysis
broader: statistics
definition: An alternative to ∗OLS regression models used when data are found in ∗nested categories or levels, such as college students taking Sociology 201, sociology majors, majors in any of the social sciences, undergraduates in the university, or undergraduates in the state. The method's advantage is that it makes it possible to separate the variance into components explaining the effects of different levels of analysis, such as the effects of a course, of a major, or of being undergraduates.
