Distributed Lag Linear and Non-Linear Models in R: The Package dlnm [PDF]

open access: yesJournal of Statistical Software, 2011
Distributed lag non-linear models (DLNMs) represent a modeling framework to flexibly describe associations showing potentially non-linear and delayed effects in time series data.

Distributed lag non-linear models. [PDF]

open access: yesStat Med, 2010
AbstractEnvironmental stressors often show effects that are delayed in time, requiring the use of statistical models that are flexible enough to describe the additional time dimension of the exposure–response relationship. Here we develop the family of distributed lag non‐linear models (DLNM), a modelling framework that can simultaneously represent non‐

Analysis of parametric biological models with non-linear dynamics [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
In this paper we present recent results on parametric analysis of biological models. The underlying method is based on the algorithms for computing trajectory sets of hybrid systems with polynomial dynamics. The method is then applied to two case studies

Falsifying cosmological models based on a non-linear electrodynamics

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Recently, the nonlinear electrodynamics (NED) has been gaining attention to generate primordial magnetic fields in the Universe and also to resolve singularity problems. Moreover, recent works have shown the crucial role of the NED on the inflation. This

The dressing method as non linear superposition in sigma models

open access: yesJournal of High Energy Physics, 2021
We apply the dressing method on the Non Linear Sigma Model (NLSM), which describes the propagation of strings on ℝ × S2, for an arbitrary seed. We obtain a formal solution of the corresponding auxiliary system, which is expressed in terms of the ...

Probabilistic time series forecasting with deep non‐linear state space models

open access: yesCAAI Transactions on Intelligence Technology, 2023
Probabilistic time series forecasting aims at estimating future probabilistic distributions based on given time series observations. It is a widespread challenge in various tasks, such as risk management and decision making.

Predicting the growth curve of body weight in madura cattle [PDF]

open access: yesKafkas Universitesi Veteriner Fakültesi Dergisi, 2021
The growth curve of livestock animals is important to evaluate the biological development managed with a farming management system. This study aimed to estimate the growth curve of body weight (BW) in Madura cattle (Bos indicus) kept at the breeding ...

Genome‐based prediction of Bayesian linear and non‐linear regression models for ordinal data

open access: yesThe Plant Genome, 2020
Linear and non‐linear models used in applications of genomic selection (GS) can fit different types of responses (e.g., continuous, ordinal, binary). In recent years, several genomic‐enabled prediction models have been developed for predicting complex ...

Non-Linear Models in Economic and Social Research

open access: yesВестник Российского экономического университета имени Г. В. Плеханова, 2022
The article shows differences of presented models from models used in exact science. It analyzes the reasons why for mathematic models of economic and social systems we cannot reach the quantitative correlation of modeling results with indicators of real
