D_{E} | Error Deviance |
D_{T} | Total Deviance |
Term | Description |
---|---|
R^{2} | the deviance R^{2} |
p | the regression degrees of freedom |
Φ | 1, for binomial and Poisson models |
D_{T} | the total deviance |
While the calculations for adjusted deviance R^{2} can produce negative values, Minitab displays zero for these cases.
The log-likelihood functions are parameterized in terms of the means. The general form of the functions follow:
The general form of the individual contributions follows:
The specific form of the individual contributions depends on the model.
