Unmanned aerial vehicle-based multispectral imagery including five spectral bands (blue, green, red, red-edge, and near-infrared) for a rice field in the ripening stage was used to develop regression models for predicting the rice yield and protein ...

A review of water quality index models and their use for assessing surface water quality
The water quality index (WQI) model is a popular tool for evaluating surface water quality. It uses aggregation techniques that allow conversion of extensive water quality data into a single value or index.

A single-index model with multiple-links
In a regression model for treatment outcome in a randomized clinical trial, a treatment effect modifier is a covariate that has an interaction with the treatment variable, implying that the treatment efficacies vary across values of such a covariate.

The Single-Index/Cox Mixture Cure Model [PDF]
AbstractIn survival analysis, it often happens that a certain fraction of the subjects under study never experience the event of interest, that is, they are considered “cured.” In the presence of covariates, a common model for this type of data is the mixture cure model, which assumes that the population consists of two subpopulations, namely the cured

Bayesian quantile regression for single-index models [PDF]
Using an asymmetric Laplace distribution, which provides a mechanism for Bayesian inference of quantile regression models, we develop a fully Bayesian approach to fitting single-index models in conditional quantile regression. In this work, we use a Gaussian process prior for the unknown nonparametric link function and a Laplace distribution on the ...

Score estimation in the monotone single‐index model [PDF]
AbstractWe consider estimation in the single‐index model where the link function is monotone. For this model, a profile least‐squares estimator has been proposed to estimate the unknown link function and index. Although it is natural to propose this procedure, it is still unknown whether it produces index estimates that converge at the parametric rate.

On Partially Linear Single-Index Models with Missing Response and Error-in-Variable Predictors
In this paper, we consider a partially linear single-index model when missing responses and nonlinear regressors with measurement error are taken into account.

Horizon states and the sign of their index in N $$ \mathcal{N} $$ = 4 dyons
Classical single centered solutions of 1/4 BPS dyons in N $$ \mathcal{N} $$ = 4 theories are usually constructed in duality frames which contain non-trivial hair degrees of freedom localized outside the horizon.
