Obtaining reliable likelihood ratio tests from simulated likelihood functions. [PDF]

open access: yesPLoS ONE, 2014
MIXED MODELS: Models allowing for continuous heterogeneity by assuming that value of one or more parameters follow a specified distribution have become increasingly popular. This is known as 'mixing' parameters, and it is standard practice by researchers-

Parameter Estimation with Data-Driven Nonparametric Likelihood Functions [PDF]

open access: yesEntropy, 2019
In this paper, we consider a surrogate modeling approach using a data-driven nonparametric likelihood function constructed on a manifold on which the data lie (or to which they are close).

Proper likelihood functions for parameter estimation in S-shaped models of unperturbed tumor growth [PDF]

open access: yesScientific Reports
The analysis of unperturbed tumor growth kinetics, particularly the estimation of parameters for S-shaped equations used to describe growth, requires an appropriate likelihood function that accounts for the increasing error in solid tumor measurements as

Poisson regression modeling of diarrhea events in pasuruan regency with maximum likelihood estimates and generalized method moment

open access: yesInternational Journal of Preventive Medicine, 2021
Context: Diarrhea characterized by a frequency increased of defecation more than 3 times/day accompanied by changes in consistency (becoming liquid). The causes of diarrhea can be divided into 2 parts, which are direct causes and indirect causes that can

Comparison Between the Exact Likelihood and Whittle Likelihood for Moving Average Processes

open access: yesStatistica, 2022
For Gaussian stationary processes, the likelihood functions include the inverse and determinant of the covariance matrices, and Whittle likelihood is considered as a standard technique to avoid expensive matrix determinant and inversions under large ...

Machine learning of log-likelihood functions in global analysis of parton distributions

open access: yesJournal of High Energy Physics, 2022
Modern analysis on parton distribution functions (PDFs) requires calculations of the log-likelihood functions from thousands of experimental data points, and scans of multi-dimensional parameter space with tens of degrees of freedom.
