Maximum-Likelihood Estimation in a Special Integer Autoregressive Model

open access: yesEconometrics, 2020
The paper is concerned with estimation and application of a special stationary integer autoregressive model where multiple binomial thinnings are not independent of one another.

Nonparametric Sieve Maximum Likelihood Estimation of Semi-Competing Risks Data

open access: yesMathematics, 2022
In biomedical studies involving time-to-event data, a subject may experience distinct types of events. We consider the problem of estimating the transition functions for a semi-competing risks model under illness-death model framework.

stochprofML: stochastic profiling using maximum likelihood estimation in R

open access: yesBMC Bioinformatics, 2021
Background Tissues are often heterogeneous in their single-cell molecular expression, and this can govern the regulation of cell fate. For the understanding of development and disease, it is important to quantify heterogeneity in a given tissue.

Disjoint Tree Mergers for Large-Scale Maximum Likelihood Tree Estimation

open access: yesAlgorithms, 2021
The estimation of phylogenetic trees for individual genes or multi-locus datasets is a basic part of considerable biological research. In order to enable large trees to be computed, Disjoint Tree Mergers (DTMs) have been developed; these methods operate ...

Semi-Nonparametric Maximum Likelihood Estimation [PDF]

open access: yesEconometrica, 1987
The density of Hermite forms: \[ h(u)=P^ 2_ k(u-\tau)\Phi^ 2(u| \tau,diag(\gamma)) \] where \(P_ k\) is a polynomial of degree K and \(\Phi\) is the density function of the multivariate normal distribution is shown to be capable of approximating any density arbitrarily closely subject to minimal qualifications relating to compactness, denseness ...

Maximum‐likelihood estimation of the geometric niche preemption model

open access: yesEcosphere, 2021
The geometric series or niche preemption model is an elementary ecological model in biodiversity studies. The preemption parameter of this model is usually estimated by regression or iteratively by using May's equation.

High-Order Maximum Likelihood Methods for Direction of Arrival Estimation

open access: yesIEEE Open Journal of Signal Processing, 2021
It is shown that using high-order statistics (higher than two) is beneficial in subspace-based Direction Of Arrival (DOA) estimation methods. Particularly, the high-order MUltiple SIgnal Classification (MUSIC) method, also known as $ 2q$-MUSIC method ...

Maximum likelihood estimation of Wiener models [PDF]

open access: yesProceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002
A Wiener model consists of a linear dynamic system followed by a static nonlinearity. The input and output are measured, but not the intermediate signal. We discuss the maximum likelihood estimate for Gaussian measurement and process noise, and the special cases when one of the noise sources is zero.

Estimation of servo-system parameters using maximum likelihood method

open access: yesVojnotehnički Glasnik, 1998
The problem of estimation of servo system parameters that cannot be measured is solved. Unknown parameters are estimated using system response measurements. A special discrete, recursive and iterative form of maximum likelihood method is presented.

Implicit Maximum Likelihood Estimation

open access: yesCoRR, 2018
Implicit probabilistic models are models defined naturally in terms of a sampling procedure and often induces a likelihood function that cannot be expressed explicitly. We develop a simple method for estimating parameters in implicit models that does not require knowledge of the form of the likelihood function or any derived quantities, but can be ...
