The computation is inspired from Cameron(2013) Chapter 5.3.4. Observed and fitted frequencies are computed and the contribution of every observed cell to the Pearson's chi-square test statistic is reported. The idea is to check if the fitted model has a tendancy to over or under predict some ranges of data
data.frame with 5 columns given the count values (Counts
),
observed frequencies (Actual
), model's prediction
(Predicted
), the difference (Diff
) and the contribution to
the Pearson's statistic (Pearson
).
