Let f(n, r, k) be the minimal number such that every hypergraph larger than f(n, r, k) contained in ([n] r ) contains a matching of size k, and let g(n, r, k) be the minimal number such that every hypergraph larger than g(n, r, k) contained in the r-partite r-graph [n]r contains a matching of size k. The Erdős-Ko-Rado theorem states that f(n, r, 2) = (n−1 r−1 ) (r ≤ n 2 ) and it is easy to show...
This paper uses simulation to explore the performance of a two-stage procedure where a preliminary Shapiro-Wilk test is used to choose between the ANOVA and Kruskal-Wallis tests as a three-sample location test. The results suggest that the two-stage procedure actually seems to be preferable when conducting such location tests.
Thrombospondin (TSP)-2 is known to be an endogenous negative regulator of vascularization in human cancer. However, it is unclear whether TSP-2 expression is related to neovascularization and prognosis in non-small cell lung cancer. In this study, we quantitatively examined the expression of TSP-2 mRNA by real-time reverse transcription-polymerase chain reaction (RT-PCR) in 102 pulmonary adenoc...
