My problems are: 1) what is the definition of
as appeared in the source code? 2) Is there any material deriving the formula implemented in code?
You can find it in HFB.c:SetBeta()
for (d = 1; d <= maxDur[i]; d++) {
x = durprob[i][d] + ApplyDAEM(hmm->transP[i][Nq]) + bqt[Nq][1];
if (q >= p->qLo[t + 1] && q <= p->qHi[t + 1]) {
for (j = 2; j < Nq; j++) {
a = ApplyDAEM(hmm->transP[i][j]);
y = bqt1[j][1];
if (a > LSMALL && y > LSMALL)
x = LAdd(x, durprob[i][d] + a + outprob[j][0][0] + y);
}
if (d < maxDur[i] && bqt1[i][d + 1] > LSMALL)
x = LAdd(x, outprob[i][0][0] + bqt1[i][d + 1]);
}
bqt[i][d] = x;

Thank you in advance!
