for a particular value of y, ytmin1, delt, compute the min part (before taking sup) in computing the upper bound of DoTT(delt), see Callaway (2017), Lemma 3
u.inner(y, ytmin1, delt, ytmin1.seq, Y1t, Y0tmin1, Y0tmin2, Y0tqteobj, F.y1, F.y0)
a value to compute the inner part of Lemma 3 for
scalar that depends on the values of y, ytmin1, and delt
