Non‐parametric regression for networks [PDF]

open access: yesStat, 2021
Network data are becoming increasingly available, and so there is a need to develop a suitable methodology for statistical analysis. Networks can be represented as graph Laplacian matrices, which are a type of manifold‐valued data. Our main objective is to estimate a regression curve from a sample of graph Laplacian matrices conditional on a set of ...

Non Parametric ROC Summary Statistics

open access: yesRevstat Statistical Journal, 2022
Receiver operating characteristic (ROC) curves are useful statistical tools for medical diagnostic testing. It has been proved its capability to assess diagnostic marker’s ability to distinguish between healthy and diseased subjects and to compare ...

Non-parametric parametricity [PDF]

open access: yesJournal of Functional Programming, 2009
AbstractType abstraction and intensional type analysis are features seemingly at odds—type abstraction is intended to guarantee parametricity and representation independence, while type analysis is inherently non-parametric. Recently, however, several researchers have proposed and implemented “dynamic type generation” as a way to reconcile these ...

On closed loop transient response system identification [PDF]

open access: yesModeling, Identification and Control, 2016
Some methods for transient closed loop step response system identification presented in the literature are reviewed. Interestingly some errors in a method published in the early 80's where propagated into a recently published method.

Investigating Temporal and Spatial Precipitation Patterns in the Southern Mid-Atlantic United States

open access: yesFrontiers in Climate, 2022
The investigation of regional vulnerability to extreme hydroclimatic events (e.g., floods and hurricanes) is quite challenging due to its dependence on reliable precipitation estimates.

A Review of Shannon and Differential Entropy Rate Estimation

open access: yesEntropy, 2021
In this paper, we present a review of Shannon and differential entropy rate estimation techniques. Entropy rate, which measures the average information gain from a stochastic process, is a measure of uncertainty and complexity of a stochastic process. We
