A Log-Gaussian Scale-Space Limiter for Hybrid Continuum--Ballistic Gas Dynamics
Bjørn Wu
We propose a log-Gaussian scale-space limiter for hybrid continuum--ballistic gas dynamics. The method defines complementary continuum and ballistic weights as Gaussian cumulative…
Graph sampling by lagged random walk
Li-Chun Zhang
We propose a family of lagged random walk sampling methods in simple undirected graphs, where transition to the next state (i.e. node) depends on both the current and previous stat…
Tests for price indices in a dynamic item universe
Li-Chun Zhang, Ingvild Johansen, Ragnhild Nygaard
There is generally a need to deal with quality change and new goods in the consumer price index due to the underlying dynamic item universe. Traditionally axiomatic tests are defin…
Almost complex structures in 6D with nondegenerate Nijenhuis tensors and large symmetry groups
Boris Kruglikov, Henrik Winther
For an almost complex structure in dimension 6 with nondegenerate Nijenhuis tensor , the automorphism group of maximal dimension is the exceptional Lie group $G…
Discussion of "On the Birnbaum Argument for the Strong Likelihood Principle"
Jan F. Bjørnstad
The paper by Mayo claims to provide a new clarification and critique of Birnbaum's argument for showing that sufficiency and conditionality principles imply the likelihood principl…
Modeling inequality and spread in multiple regression
Rolf Aaberge, Steinar Bjerve, Kjell Doksum
We consider concepts and models for measuring inequality in the distribution of resources with a focus on how inequality varies as a function of covariates. Lorenz introduced a dev…
