WebNov 15, 2024 · For example, in our regression model we can observe the following values in the output for the null and residual deviance: Null deviance: 43.23 with df = 31. Residual deviance: 16.713 with df = 29. We can use these values to calculate the X2 statistic of the model: X2 = Null deviance – Residual deviance. X2 = 43.23 – 16.713.
