2020 journal article

On empirical estimation of mode based on weakly dependent samples

COMPUTATIONAL STATISTICS & DATA ANALYSIS, 152.

By: B. Liu n & S. Ghosh n 

author keywords: Bernstein polynomials; Empirical mode estimator; Strong consistency; Anderson-Darling test
TL;DR: A non-parametric estimate of thedensity is proposed based on a sequence of mixtures of Beta densities which allows for the estimation of the mode even when the mode is possibly located on the boundary of the support of the density. (via Semantic Scholar)

2019 journal article

A functional mixed model for scalar on function regression with application to a functional MRI study

BIOSTATISTICS, 22(3), 439–454.

By: W. Ma n, L. Xiao n , B. Liu n & M. Lindquist*

author keywords: fMRI; Functional data analysis; Functional mixed model; Functional principal component; Repeated measurements; Variance component testing
MeSH headings : Brain / diagnostic imaging; Computer Simulation; Humans; Magnetic Resonance Imaging; Principal Component Analysis
TL;DR: The model extends the standard scalar on function regression for repeated outcomes by incorporating subject-specific random functional effects and can be reformulated as a mixed effects model and thus easily fit. (via Semantic Scholar)
