This is a supplementary document for explaining what we could not contain in the main paper. I. BASIC FUNCTIONS AND NOTATIONS In this section, we first define some useful functions that will be used for FDR calculation. A. fSum functions 1) fSum1 function: fSum1(x, y, l) = l a=0 xa yl−a = yl l a=0 x y a = gSum1 x y , y, l (1) 2) fSum2 function: fSum2(x, y, z, l) = l a=0 a b=0 xb ya−b zl−a = zl l a=0 a b=0 y z a x y b = gSum2 y z , x y , z, l (2) 3) fSum3 function: fSum3(x, y, z, p, l) = l a=0 a b=0 b c=0 xc yb−c za−b pl−a = pl l a=0 a b=0 b c=0 z p a y z b x y c = gSum3 z p , y z , x y , p, l (3) 4) fSum4 function: fSum4(x, y, z, p, q, l) = l a=0 a b=0 b c=0 c d=0 xd yc−d zb−c pa−b ql−a = ql l a=0 a b=0 b c=0 c d=0 p q a z p b y z c x y d = gSum4 p q , z p , y z , x y , q, l (4) 5) fSum5 function: fSum5(x, y, z, p, q, r, l) = l a=0 a b=0 b c=0 c d=0 d e=0 xe yd−e zc−d pb−c qa−b rl−a = rl l a=0 a b=0 b c=0 c d=0 d e=0 q r a p q b z p c y z d x y e = gSum...
