A hidden Markov modeling approach for identifying tumor subclones in next-generation sequencing studies
收藏 引用
BIOSTATISTICS 2022年 第1期23卷 69-82页
作者: Choo-Wosoba, Hyoyoung Albert, Paul S. Zhu, Bin NCI Biostat Branch Div Canc Epidemiol & Genet 9609 Med Ctr Dr Rockville MD 20850 USA
Allele-specific copy number alteration (ASCNA) analysis is for identifying copy number abnormalities in tumor cells. Unlike normal cells, tumor cells are heterogeneous as a combination of dominant and minor subclones ... 详细信息

A sequential smoothing algorithm with linear computational cost
收藏 引用
BIOMETRIKA 2010年 第2期97卷 447-464页
作者: Fearnhead, Paul Wyncoll, David Tawn, Jonathan Univ Lancaster Dept Math & Stat Lancaster LA1 4YF England
In this paper we propose a new particle smoother that has a computational complexity of O(N), where N is the number of particles. This compares favourably with the O(N-2) computational cost of most smoothers. The new ... 详细信息

ANNALS OF APPLIED STATISTICS 2019年 第3期13卷 1397-1429页
作者: Patel, Lekha Gustafsson, Nils Lin, Yu Ober, Raimund Henriques, Ricardo Cohen, Edward Imperial Coll London Dept Math London SW7 2AZ England UCL MRC Lab Mol Cell Biol London WC1E 6BT England European Mol Biol Lab Cell Biol & Biophys D-69117 Heidelberg Germany Texas A&M College Stn TX USA Univ Southampton Ctr Canc Immunol Fac Med Southampton Hants England Francis Crick Inst London NW1 1AT England Texas A&M Univ Dept Biomed Engn College Stn TX 77843 USA
Fluorescing molecules (fluorophores) that stochastically switch between photon-emitting and dark states underpin some of the most celebrated advancements in super-resolution microscopy. While this stochastic behavior ... 详细信息

The generalized viscosity explicit rules for solving variational inclusion problems in Banach spaces
收藏 引用
OPTIMIZATION 2021年 第12期70卷 2607-2633页
作者: Cholamjiak, Prasit Pholasa, Nattawut Suantai, Suthep Sunthrayuth, Pongsakorn Univ Phayao Sch Sci Phayao Thailand Chiang Mai Univ Fac Sci Dept Math Res Ctr Math & Appl Math Chiang Mai Thailand Rajamangala Univ Technol Thanyaburi RMUTT Fac Sci & Technol Dept Math & Comp Sci Thanyaburi Pathumthani Thailand
In this paper, we propose a generalized viscosity explicit method for finding zeros of the sum of two accretive operators in the framework of Banach spaces. The strong convergence theorem of such method is proved unde... 详细信息

A Dynamical System Associated with the Fixed Points Set of a Nonexpansive Operator
收藏 引用
JOURNAL OF DYNAMICS AND DIFFERENTIAL EQUATIONS 2017年 第1期29卷 155-168页
作者: Bot, Radu Ioan Csetnek, Ernoe Robert Univ Vienna Fac Math Oskar Morgenstern Pl 1 A-1090 Vienna Austria
We study the existence and uniqueness of (locally) absolutely continuous trajectories of a dynamical system governed by a nonexpansive operator. The weak convergence of the orbits to a fixed point of the operator is i... 详细信息

Selection of Variables for Cluster Analysis and Classification Rules
收藏 引用
JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION 2008年 第483期103卷 1294-1303页
作者: Fraiman, Ricardo Justel, Ana Svarc, Marcela Univ San Andres Buenos Aires DF Argentina Univ Republica Ctr Matemat Montevideo Uruguay Univ Autonoma Madrid Madrid Spain
In this article we introduce two procedures for variable selection in cluster analysis and classification rules. One is mainly aimed at detecting the ''noisy'' noninformative variables, while the other... 详细信息

Computational methods for complex stochastic systems: a review of some alternatives to MCMC
收藏 引用
STATISTICS AND COMPUTING 2008年 第2期18卷 151-171页
作者: Fearnhead, Paul Univ Lancaster Dept Math & Stat Lancaster LA1 4YF England
We consider analysis of complex stochastic models based upon partial information. MCMC and reversible jump MCMC are often the methods of choice for such problems, but in some situations they can be difficult to implem... 详细信息

Filtering recursions for calculating likelihoods for queues based on inter-departure time data
收藏 引用
STATISTICS AND COMPUTING 2004年 第3期14卷 261-266页
作者: Fearnhead, P Univ Lancaster Dept Math & Stat Lancaster LA1 4YF England
We consider inference for queues based on inter-departure time data. Calculating the likelihood for such models is difficult, as the likelihood involves summing up over the (exponentially-large) space of realisations ... 详细信息
