Variable selection for the single-index model [PDF]
Biometrika, 2007 We consider variable selection in the single-index model. We prove that the popular leave-m-out crossvalidation method has different behaviour in the single-index model from that in linear regression models or nonparametric regression models. A new consistent variable selection method, called separated crossvalidation, is proposed.

The Single Index Market Model in Agriculture [PDF]
Northeastern Journal of Agricultural and Resource Economics, 1988 This study illustrates the differences in empirical results due to data measurements and estimating procedures when applying the single index market model in agriculture. Gross and net return betas along with systematic and unsystematic risk proportions are estimated and found to be different.

Semiparametric Integrated and Additive Spatio-Temporal Single-Index Models
Mathematics, 2023 In this paper, we introduce two semiparametric single-index models for spatially and temporally correlated data. Our first model has spatially and temporally correlated random effects that are additive to the nonparametric function, which we refer to as ...

Analysis of Double Single Index Models [PDF]
Scandinavian Journal of Statistics, 2016 Abstract Motivated from problems in canonical correlation analysis, reduced rank regression and sufficient dimension reduction, we introduce a double dimension reduction model where a single index of the multivariate response is linked to the multivariate covariate through a single index of these covariates, hence the name double ...

A short note on fitting a single-index model with massive data
Statistical Theory and Related Fields, 2023 This paper studies the inference problem of index coefficient in single-index models under massive dataset. Analysis of massive dataset is challenging owing to formidable computational costs or memory requirements.

Single Index Regression Model for Functional Quasi-Associated Times Series Data
Revstat Statistical Journal, 2023 The mixing condition is often considered to modeling the functional time series data. Alternatively, in this work we consider the problem of nonparametric estimation of the regression function in Single Functional Index Model (SFIM) under the quasia ...

A bootstrap test for single index models [PDF]
Statistics, 2001 Single index models are frequently used in econometrics and biometrics. Logit and Probit models arc special cases with fixed link functions. In this paper we consider a bootstrap specification test that detects nonparametric deviations of the link function.
