The formula given for the lower bound on page 21 is not consistent with that given on page 22. On page 21, it is showing, max((SUM ui) + 1 - N, 0) while on page 22, it is showing, max((SUM Fxi) -1, 0) the formula on page 21 for the lower bound should be, max((SUM ui) -1, 0)
Yes and no. The first formula on p21 is the generic form of the lower bound. As the copula is only defined in 2-dimensions, then N=2 and you end up with the formula you have stated.
