    Implications of three causal models for the measurement of halo error
    (1990) Fisicaro, Sebastiano A.; Lance, Charles E.
    The appropriateness of a traditional correlational measure of halo error (the difference between dimensional rating intercorrelations and dimensional true score intercorrelations) is reexamined in the context of three causal models of halo error. Mathematical derivations indicate that the traditional correlational measure typically will underestimate halo error in ratings and can suggest no halo error or even "negative" halo error when positive halo error actually occurs. A corrected correlational measure is derived that avoids these problems, and the traditional and corrected measures are compared empirically. Results suggest that use of the traditional correlational measure of halo error be discontinued. Index terms: halo, halo effect, halo error, performance ratings, rating accuracy, rating errors.

    Residual centering, exploratory and confirmatory moderator analysis, and decomposition of effects in path models containing interactions
    (1988) Lance, Charles E.
    Hierarchical moderated regression (HMR) analysis may lead to interpretational problems in tests of moderator (interaction) hypotheses. An alternative, residual- centering approach is described and compared to traditional HMR analysis. Procedures for evaluating interaction hypotheses and general effect analysis procedures are described for path (causal) models containing interactions. Index terms: Confirmatory analysis, Effect analysis in path models, Goodness-of-fit tests, Hierarchical moderated regression, Mediators, Moderated regression, Multicollinearity, Path models, Residual centering.
