Estimation and inference for the mediation effect in a time-varying mediation model

open access: yesBMC Medical Research Methodology, 2022
Background Traditional mediation analysis typically examines the relations among an intervention, a time-invariant mediator, and a time-invariant outcome variable.

Can neurofeedback provide evidence of direct brain-behavior causality?

open access: yesNeuroImage, 2022
Neurofeedback is a procedure that measures brain activity in real-time and presents it as feedback to an individual, thus allowing them to self-regulate brain activity with effects on cognitive processes inferred from behavior.

Indirect likelihood inference (revised) [PDF]

open access: yes, 2013
Standard indirect Inference (II) estimators take a given finite-dimensional statistic, Z_{n} , and then estimate the parameters by matching the sample statistic with the model-implied population moment. We here propose a novel estimation method that utilizes all available information contained in the distribution of Z_{n} , not just its first moment ...

Inference of a Boolean Network From Causal Logic Implications

open access: yesFrontiers in Genetics, 2022
Biological systems contain a large number of molecules that have diverse interactions. A fruitful path to understanding these systems is to represent them with interaction networks, and then describe flow processes in the network with a dynamic model ...

Efficient Simulation-Based Minimum Distance Estimation and Indirect Inference [PDF]

open access: yes, 2009
Given a random sample from a parametric model, we show how indirect inference estimators based on appropriate nonparametric density estimators (i.e., simulation-based minimum distance estimators) can be constructed that, under mild assumptions, are ...

Super-Selective Reconstruction of Causal and Direct Connectivity With Application to in vitro iPSC Neuronal Networks

open access: yesFrontiers in Neuroscience, 2021
Despite advancements in the development of cell-based in-vitro neuronal network models, the lack of appropriate computational tools limits their analyses.

Estimating Functions in Indirect Inference

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2004
SummaryThere are models for which the evaluation of the likelihood is infeasible in practice. For these models the Metropolis–Hastings acceptance probability cannot be easily computed. This is the case, for instance, when only departure times from a G/G/1 queue are observed and inference on the arrival and service distributions are required.

Inverse Ising inference with correlated samples

open access: yesNew Journal of Physics, 2014
Correlations between two variables of a high-dimensional system can be indicative of an underlying interaction, but can also result from indirect effects. Inverse Ising inference is a method to distinguish one from the other.
