The goodness-of-fit test based on deviance is a likelihood-ratio test between the fitted model & the saturated one (one in which each observation gets its own parameter). Pearson's test is a score test; the expected value of the score (the first derivative of the log-likelihood function) is zero if the fitted model is ...
