Cressie-read power divergence
Websummary The Power divergence family of statistics was introduced by Cressie and Read in 1984. The likelihood ratio statistic and the Pearson’s chi-squared statistic are examples of the many members of the power divergency family which are linked. WebJul 1, 2006 · A sample version of the power-divergence measures of Cressie and Read is proposed for the influence analysis in the logistic regression model.

WebCressie and Read p. 85: extreme values of λ are most useful for detecting deviations from an expected cell frequency in a single cell (i.e., bump or dip alternatives). Use of the maximum cell frequency to test for "spikes" is discussed by Levin (1983); he also derives the appropriate distributional results for hypothesis testing. trust in a gust stallionWebpathway information from limited noisy observational data, we use the Cressie-Read (CR)-information theoretic entropy family of divergence measures as a distributional basis for linking the data and the unknown and unobservable behavioral network edge-path probabilities.
