Asymptotics for likelihood ratio tests of boundary points with singular information and unidentifiable nuisance parameters
Karl Oskar Ekvall, Ola Hössjer, Matteo Bottai +1
We establish the asymptotic distribution of likelihood ratio tests when nuisance parameters are unidentifiable under the null hypothesis, parameters of interest lie on the boundary…
A Comparison Between Quantile Regression and Linear Regression on Empirical Quantiles for Phenological Analysis in Migratory Response to Climate Change
Måns Karlsson, Ola Hössjer
It is well established that migratory birds in general have advanced their arrival times in spring, and in this paper we investigate potential ways of enhancing the level of detail…
Identification of taxon through classification with partial reject options
Måns Karlsson, Ola Hössjer
Identification of taxa can significantly be assisted by statistical classification based on trait measurements in two major ways; either individually or by phylogenetic (clustering…
Quantifying and estimating additive measures of interaction from case-control data
Ola Hössjer, Lars Alfredsson, Anna Karin Hedström +3
In this paper we develop a general framework for quantifying how binary risk factors jointly influence a binary outcome. Our key result is an additive expansion of odds ratios as a…
Nonlinearly Perturbed Birth-Death-Type Models
Dmitrii Silvestrov, Mikael Petersson, Ola Hössjer
Asymptotic expansions for stationary and conditional quasi-stationary distributions of nonlinearly perturbed birth-death-type semi-Markov models are presented. Applications to mode…
