Questioning Multilevel Models

Questioning the “General Arousal” Models

The paper argues that the concept of “general arousal”, or Extraversion, which is used to present energetic aspects of behaviour is an oversimplification of the energetic components of temperament. Two reported studies were conducted on Russian and Canadian samples using the Structure of Temperament Questionnaire Compact (STQ-77), which has 12 activity-specific temperament scales assessing vari...

Multilevel covariance component models

Goldstein (1986) describes the analysis of the multilevel mixed effects linear model with random coefficients, where the variance and covariance components have a nested structure across levels. The purpose of the present note is to show how a simple extension to the formulae in that paper can accommodate cross-classifications of the components within any level of the nesting, thus enabling qui...
