Simultaneous Regression and Selection in Nonlinear Modal Model Identification

open access: yesVibration, 2021
High fidelity finite element (FE) models are widely used to simulate the dynamic responses of geometrically nonlinear structures. The high computational cost of running long time duration analyses, however, has made nonlinear reduced order models (ROMs ...

Seasonal prediction of winter extreme precipitation over Canada by support vector regression [PDF]

open access: yesHydrology and Earth System Sciences, 2011
For forecasting the maximum 5-day accumulated precipitation over the winter season at lead times of 3, 6, 9 and 12 months over Canada from 1950 to 2007, two nonlinear and two linear regression models were used, where the models were support vector ...

Biomass allometric models for Larix rupprechtii based on Kosak’s taper curve equations and nonlinear seemingly unrelated regression

open access: yesFrontiers in Plant Science, 2023
The diameter at breast height (DBH) is the most important independent variable in biomass allometry models based on metabolic scaling theory (MST) or geometric theory. However, the fixed position DBH can be misleading in its use of universal scaling laws

Pendeteksian Outlier pada Regresi Nonlinier dengan Metode statistik Likelihood Displacement

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2012
Outlier is an observation that much different (extreme) from the other observational data, or data can be interpreted that do not follow the general pattern of the model. Sometimes outliers provide information that can not be provided by other data. That'

Fitting Nonlinear Equations with the Levenberg–Marquardt Method on Google Earth Engine

open access: yesRemote Sensing, 2022
Google Earth Engine (GEE) has been widely used to process geospatial data in recent years. Although the current GEE platform includes functions for fitting linear regression models, it does not have the function to fit nonlinear models, limiting the GEE ...

Review of guidance papers on regression modeling in statistical series of medical journals

open access: yesPLoS ONE, 2022
Although regression models play a central role in the analysis of medical research projects, there still exist many misconceptions on various aspects of modeling leading to faulty analyses.
