eqValBound
and withReplaceBound
find a pvalue by
changing the original constraint (that the total difference is greater than the margin),
instead placing a restriction on the
number of batches with error no larger than t
.
eqValBound
finds an exact solution with this restriction,
whereas withReplaceBound
finds a more conservative bound.
See Stark for more details about withReplaceBound
.
