WebFeb 14, 2024 · This increase in deviance is evidence of a significant lack of fit. We can also use the residual deviance to test whether the null hypothesis is true (i.e. Logistic regression model provides an adequate fit for the data). This is possible because the deviance is given by the chi-squared value at a certain degrees of freedom.
