本文给出了联合生存函数G(t(1),t(2),…,t(r))与P(X(1)> t(1),X(2)> t(2),.,X(r)> t(r)),对于与P(X(j)> t)相同的边际生存函数S(j)(t),j = 1,2,.,r,当子生存函数S(j)(*)(t)与P(X(j)> t)相同时,X(j)= min(k= 1,2),.,(r)X(k))是固定的。定理1给出了r = 2的界,定理2给出了一般r的界。定理3将所得结果应用于竞争风险问题,并给出了基于观测值的经验界。最后,通过一个例子说明了边界。
This paper gives sharp bounds for the joint survival function G(t(1), t(2),...,t(r)) identical with P(X(1) > t(1), X(2) > t(2),...,X(r) > t(r)), and for the marginal survival functions S(j)(t) identical with P(X(j) > t), j = 1,2,...,r, when the sub-survival functions S(j) (*)(t) identical with P(X(j) > t, X(j) = min(k=1,2),...,(r)X(k)) are fixed. Theorem 1 gives the bounds for r = 2, and Theorem 2 gives the bounds for general r. Theorem 3 applies the result to the competing risks problem, and presents empirical bounds based on the observations. Finally, an example illustrates the bounds.
