Published in 2018 at "Statistics in medicine"

DOI: 10.1002/sim.7584

Abstract: Missing covariate values are prevalent in regression applications. While an array of methods have been developed for estimating parameters in regression models with missing covariate data for a variety of response types, minimal focus has… read more here.

Published in 2019 at "Statistical Papers"

DOI: 10.1007/s00362-016-0848-6

Abstract: This paper considers the testing problem of partially linear models with missing covariates. The inverse probability weighted restricted estimator for the parametric component under linear constraint is derived and proven to share asymptotically normal distribution.… read more here.

Published in 2022 at "IEEE Signal Processing Letters"

DOI: 10.1109/lsp.2022.3204408

Abstract: Multi-direction iterative (MUL-DI) algorithm is an efficient algorithm for large-scale models, and it establishes a theoretical linkage between least squares (LS) and gradient descent (GD) algorithms. However, it involves Givens transformation and dense matrix calculation… read more here.
