Differences in Total Factor Productivity and the Pattern of International Trade

open access: yesEconomies
In this work, we develop a trade model that explains the pattern of trade between countries based on differences in total factor productivity (TFP) while also accounting for differences in relative factor endowments.

Rank Tests of Dispersion

open access: yesThe Annals of Mathematical Statistics, 1963
Summary: In a recent paper [Ann. Math. Stat. 31, 1174--1189 (1960; Zbl 0104.37302)] \textit{A. R. Ansari} and \textit{R. A. Bradley} have shown the equivalence of two rank tests for comparing dispersion, one test due to \textit{D. E. Barton} and \textit{F. N. David} [Ann. Hum. Genet. 22, 250--257 (1958; Zbl 0081.14205)], the other to Ansari and Freund,

Rank Tests for Nonlinear Cointegration [PDF]

open access: yesJournal of Business & Economic Statistics, 2001
A test procedure based on ranks is suggested to test for nonlinear cointegration. For two (or more) time series it is assumed that monotonic transformations exist such that the normalized series can asymptotically be represented as Wiener processes. Rank-test procedures based on the difference between the sequences of ranks are suggested.

Convex Rank Tests and Semigraphoids [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2009
Convex rank tests are partitions of the symmetric group which have desirable geometric properties. The statistical tests defined by such partitions involve counting all permutations in the equivalence classes. Each class consists of the linear extensions of a partially ordered set specified by data.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
