Abstract:
Let
Xi,
i≥1 be a sequence of i.i. d. r.v.’s satisfying
q=P(
Xi=0)=1-P(
Xi=1),
q is unknown. Suppose that
An:1≤
n≤
n0 and
Rn:1≤
n≤
n0 are any two sets of numbers satisfying
A1≤
A2≤…≤
An0,0<
R1≤
R2≤…≤
Rn0,
Ai<
Ri(
i=1,…,
no-1) and
An0=Rno
Rn0.
For the hypothesis
H0:
q≥
q0(0<
q0<1), We consider the sequential test △=(
r,
d) in which
r=min{
n:
n1,
Dn≤
Anor
Dn≥
Rn,
d=I
(Dr≥Rr), where D_n=\sum_i=1^n X_i(n \geq 1).
IA is the indicator of set
A, “
d =1” means rejecting
H0 and “
d = 0” means accepting
H0. In the present paper, we find out the optimal lower (upper) confidence limits for
q based on data (
r,
Dr) in some sence
