Maximal Information Divergence from Statistical Models defined by Neural Networks
neural network exponential family Kullback-Leibler diver-gence multi-information
2013/4/27
We review recent results about the maximal values of the Kullback-Leibler information divergence from statistical models defined by neural networks, including naive Bayes models, restricted Boltzmann ...
Perturbation of matrices and non-negative rank with a view toward statistical models
Euclidean topology Jacobian matrix mixture models
2010/10/19
In this paper we study how perturbing a matrix changes its non-negative rank. We show that the non-negative rank is upper-semicontinuos and we describe some special families of perturbations. We apply...
Statistical models defined by sufficiency。
Consistency of statistical models described by families of reversed submartingales
Consistency of statistical models families of reversed submartingales
2009/9/22
A large number of statistical models is described by
a family of reversed submartingales converging to degenerated limits.
The problem under consideration is to estimate the maximum points
of the l...
Inference on a Set of Statistical Models
AIC CIC confidence set of models generalized likelihood ratio test GIC information criteria
2009/3/5
The paper outlines some aspects related to statistical model selection, focusing in particular on inference conducted in the presence of a finite set of parametric models. The point the paper emphasiz...
Statistical models to study subtoxic concentrations for some standard mutagens in three colon cancer cell lines
Inverse regression problem subtoxic concentration confidence interval
2009/2/23
The aim of this work is to propose models to study the toxic effect of different concentrations of some standard mutagens in different colon cancer cell lines. We find estimates and, by means of an in...
Algebraic statistical models
Algebraic statistics computational algebraic geometry exponential family maximum likelihood estimation
2010/4/27
Many statistical models are algebraic in that they are defined in terms of polynomial
constraints, or in terms of polynomial or rational parametrizations. The parameter spaces of
such models are typ...
Combining domain knowledge and statistical models in time series analysis
time series analysis domain knowledge empirical models mechanisticmodels combined substantive-empirical approach basis function
2010/4/27
This paper describes a new approach to time series modeling that
combines subject-matter knowledge of the system dynamics with statistical
techniques in time series analysis and regression. Applicat...
A comparison of statistical models for short categorical or ordinal time series with applications in ecology
time series categorical variable ordinal variable regression model Markov chain auto-regressive process estimation
2010/4/27
We study two statistical models for short-length categorical (or ordinal) time series. The first one is a regression
model based on generalized linear model. The second one is a parametrized Markovia...
