This paper dealt with the existence of positive solutions for the nonlinear eigenvalue problem and the superlinear semipositone problem of an $n$th-order delay differential equation. The main results in this paper generalize some of the existing results in the literature. The proofs are based on the well-known Guo-Krasnoselskii fixed-point theorem.
