    The change-of-variance function for dependent data

    The infinitesimal stability of the asymptotic variance is considered forM-estimators of a location parameter when the nominal sample with i.i.d. data is contaminated by a possibly dependent process. It is shown t...

    Asymptotic bias and variance for a general class of varying bandwidth density estimators

    We consider a general class of varying bandwidth estimators of a probability density function. The class includes the Abramson estimator, transformation kernel density estimator (TKDE), Jones transformation ke...

    Information and effective number of meioses in linkage analysis

    In this paper we introduce two information criteria in linkage analysis. The setup is a sample of families with unusually high occurrence of a certain inheritable disease. Given phenotypes from all families, t...

    Methodological study of affine transformations of gene expression data with proposed robust non-parametric multi-dimensional normalization method

    Low-level processing and normalization of microarray data are most important steps in microarray analysis, which have profound impact on downstream analysis. Multiple methods have been suggested to date, but i...

    Probabilistic Choice with an Infinite Set of Options: An Approach Based on Random Sup Measures

    This chapter deals with probabilistic choice when the number of options is infinite. The choice space is a compact set $$S\subseteq \mathbb {R...

    Analysis of the Stochasticity of Mortality Using Variance Decomposition

    We analyse the stochasticity in mortality data from the USA, the UK and Sweden, and in particular to which extent mortality rates are explained by systematic variation, due to various risk factors, and random ...

    The genetic interacting landscape of 63 candidate genes in Major Depressive Disorder: an explorative study

    Genetic contributions to major depressive disorder (MDD) are thought to result from multiple genes interacting with each other. Different procedures have been proposed to detect such interactions. Which approa...

    Spatial Autocorrelation for Subdivided Populations with Invariant Migration Schemes

    For populations with geographic substructure and selectively neutral genetic data, the short term dynamics is a balance between migration and genetic drift. Before fixation of any allele, the system enters int...

    A significant risk locus on 19q13 for bipolar disorder identified using a combined genome-wide linkage and copy number variation analysis

    The genetic background to bipolar disorder (BPD) has been attributed to different genetic and genomic risk factors. In the present study we hypothesized that inherited copy number variations (CNVs) contribute ...

    Phase-Type Distribution Approximations of the Waiting Time Until Coordinated Mutations Get Fixed in a Population

    In this paper we study the waiting time until a number of coordinated mutations occur in a population that reproduces according to a continuous time Markov process of Moran type. It is assumed that any individ...
