Sentence examples for negative variance from inspiring English sources

In many cases, such negative variance components can be translated as negative within-unit correlations.

It is established that such negative variance components in generalized linear mixed models can occur in practice and that they can be estimated using standard statistical software.

It is shown that negative variance components, with corresponding negative associations, can occur in hierarchical models for non-Gaussian outcomes as well, such as repeated binary data or counts.
