Dear Forum,

I am not sure if I can post this question here. I have a data of Good and Bad's and I have calculated Gini Coefficient and Coefficient of Concordance. The Gini Coefficient is as low as 0.29 while CoC is 0.64. 

My data is as given below

df = data.frame(ratings = c("C", "B", "BB", "BB+", "BBB", "A", "AA", "AA+", "AAA"), total = c(1, 15, 127, 272, 939, 387, 109, 27, 6), good = c(1, 14, 122, 267, 934, 386, 109, 27, 6), bad = c(0, 1, 5, 5, 5, 1, 0, 0, 0))

I am sort of confused now that CoC is as high as 0.64 whereas Gini is low.

I sincerely apologize to the forum, if this question should not have appeared here.

Regards

Katherine
