Logistic regression vs chi square analysis

WitrynaThe above example involves a logistic regression model, however, these tests are very general, and can be applied to any model with a likelihood function. Note that even models for which a likelihood or a log likelihood is not typically displayed by statistical software (e.g., ordinary least squares regression) have likelihood functions.

WitrynaFrom this table, we may conclude that: The Null model clearly does not fit. Adding B to the Null model drops the deviance by 36.41 − 28.80 = 7.61, which is highly significant because \(P(\chi^2_1 \geq 7.61)=0.006\).
