Estimation of a functional single index model with dependent errors and unknown error density [PDF]
Communications in statistics. Simulation and computation, 2018 The problem of error density estimation for a functional single index model with dependent errors is studied. A Bayesian method is utilized to simultaneously estimate the bandwidths in the kernel-form error density and regression function, under an ...

ROBUST VARIABLE SELECTION FOR SINGLE INDEX SUPPORT VECTOR REGRESSION MODEL
Al-Mustansiriyah Journal of Science, 2019 The single index support vector regression model (SI-SVR) is a useful regression technique used to alleviate the problem of high-dimensionality. In this paper, we propose a robust variable selection technique for the SI-SVR model by using vital method to

ACM Transactions on Knowledge Discovery from DataSingle-index models (SIMs) have been widely used in various applications due to their simplicity and interpretability. However, despite the potential for SIMs to result in discriminatory outcomes based on sensitive attributes like gender, race, or ethnicity, the issue of fairness has not been thoroughly examined in recent studies on the topic.
