Review | SpringerLinkMultilevel models also known as hierarchical linear models , linear mixed-effect model , mixed models , nested data models , random coefficient , random-effects models , random parameter models , or split-plot designs are statistical models of parameters that vary at more than one level. These models can be seen as generalizations of linear models in particular, linear regression , although they can also extend to non-linear models. These models became much more popular after sufficient computing power and software became available. Multilevel models are particularly appropriate for research designs where data for participants are organized at more than one level i. Individual differences in growth curves may be examined.

Summer 2011 PIER Hierarchical Models Workshop
Specifically, the primary objective of the course is to illustrate ways in which multilevel models help addressing questions in teacher and school effects research, in Application of Hierarchical Linear Models to Assessing Change Anthony S. Hierarchical or multilevel modeling provides a method for researchers to account for possible within-group correlations while also explicitly modeling group-level attributes and membership, acknowledging the potential importance of contextual effects on lower-level outcomes. Nested datasets are increasingly Get this from a library! Multilevel and longitudinal modeling using stata. The hierarchical regression is model comparison of nested regression models.
Item Response Theory IRT is increasingly applied in health research to combine information from multiple-item responses. IRT posits that a person's susceptibility to a symptom is driven by the interaction of the characteristics of the symptom and person. This article describes the statistical background of incorporating IRT into a multilevel framework and extends this approach to longitudinal health outcomes, where the self-report method is used to construct a multi-item scale. A secondary analysis of data from 2 descriptive longitudinal studies is performed. The data include 21 symptoms reported across time by women with breast cancer. A 3-level hierarchical linear model HLM was used for the analysis. Level 1 models the item responses, consisting of symptom presence or absence.
