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 ...

Minimally capturing heterogeneous complier effect of endogenous treatment for any outcome variable
Journal of Causal Inference, 2023 When a binary treatment DD is possibly endogenous, a binary instrument δ\delta is often used to identify the “effect on compliers.” If covariates XX affect both DD and an outcome YY, XX should be controlled to identify the “XX-conditional complier ...

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.

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 ...

Risk Costs and the Choice of Market Return Index
Journal of Agricultural and Resource Economics, 1992 Six measures of returns are used to estimate the most "appropriate" market index for southeast Kansas farms. Results suggest that localized indices are more appropriate than state indices for use as the market index.

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.
