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.

You can arrive at a simple proof by induction, using the more basic theorem that: a × b mod n = ( a mod n) × ( b mod n) mod n. With that, then the inductive proof goes as: It is true for e = 1. This can be seen as: m 1 mod n = ( m mod n) 1 mod n. If it is true from e = k − 1, then it is true for e = k.
