Nonparametric Regression with Measurement Error in Banach Spaces
Pratim Guha Niyogi, Priyadarshi Dey
We consider nonparametric regression with a Banach-space-valued predictor where the covariate takes values in a general separable Banach space. Our primary objective is to develop…
Covariate-Adjusted Functional Principal Components Analysis for Modeling Hazard Rates of Physical Activity in the US Population
Md Rokibul Hasan, Pratim Guha Niyogi
Physical activity plays a vital role in human health. Its entire distribution differs among people. Commonly used summary measures cannot describe this distributional pattern. We p…
Scalar-on-distribution regression via generalized odds with applications to accelerometry-assessed disability in multiple sclerosis
Pratim Guha Niyogi, Muraleetharan Sanjayan, Kathryn C. Fitzgerald +2
Distributional representations of data collected using digital health technologies have been shown to outperform scalar summaries for clinical prediction, with carefully quantified…
Hazard and Beyond: Exploring Five Distributional Representations of Accelerometry Data for Disability Discrimination in Multiple Sclerosis
Pratim Guha Niyogi, Muraleetharan Sanjayan, Dmitri Volfson +3
Research on modeling the distributional aspects in sensor-based digital health (sDHT) data has grown significantly in recent years. Most existing approaches focus on using individu…
Identifying arbitrary transformation between the slopes in scalar-on-function regression
Pratim Guha Niyogi, Subhra Sankar Dhar
In this article, we study whether the slope functions of two scalar-on-function regression models in two samples are associated with any arbitrary transformation along the vertical…
Quadratic inference with dense functional responses
Pratim Guha Niyogi, Ping-Shou Zhong
We address the challenge of estimation in the context of constant linear effect models with dense functional responses. In this framework, the conditional expectation of the respon…
