Robust Estimation and Inference for Semiparametric and Nonparametric Regression Models

Mathematics
Parametric regression methods are efficient when correctly specified but are sensitive to model misspecification and outliers. Nonparametric regression offers greater flexibility at the cost of reduced interpretability and susceptibility to the curse of ...

Determining factors associated with the number of oocytes with appropriate morphology in infertile women: A cross-sectional study

International Journal of Reproductive BioMedicine
Background: Infertility affects millions of couples worldwide. The number of morphologically normal oocytes (MNO) is a key determinant of assisted reproductive technology success. Accurate identification of influencing factors is limited by excess zeros

Influence Analysis Using Liu–Ridge Estimators in Semiparametric Regression Models

Journal of Mathematics
Influential observations and the multicollinearity among predictors in semiparametric regression models (SPRMs) often lead to biased and unstable coefficient estimates, as well as distorted patterns in leverage and residuals.
