A remark on semiparametric models

Journal of Multivariate Analysis, 1986
Consider a semiparametric model (X,A,\({\mathcal P})\) with interesting Euclidean parameter \(\kappa\) : \({\mathcal P}\to R_ k\) to be estimated. Assume that \({\mathcal P}\) is a differentiable family of mutually absolutely continuous probability measures and the parameter \(\kappa\) is a functional on \({\mathcal P}\).

Semiparametric Estimation with Generated Covariates [PDF]

In this paper, we study a general class of semiparametric optimization estimators of a vector-valued parameter. The criterion function depends on two types of infinite-dimensional nuisance parameters: a conditional expectation function that has been ...

Computing nonparametric functional estimates in semiparametric problems. [PDF]

We offer a set of FORTRAN routines which compute nonparametric estimates of a number of functionals. The routines are primarily intended to be used in the estimation of semiparametric models.

Breast cancer survival analysis: Applying the generalized gamma distribution under different conditions of the proportional hazards and accelerated failure time assumptions

International Journal of Preventive Medicine, 2012
Background: The goal of this study is to extend the applications of parametric survival models so that they include cases in which accelerated failure time (AFT) assumption is not satisfied, and examine parametric and semiparametric models under ...

Endogenous semiparametric binary choice models with heteroscedasticity [PDF]

In this paper we consider endogenous regressors in the binary choice model under a weak median exclusion restriction, but without further specification of the distribution of the unobserved random components.

Efficient estimation of semiparametric conditional moment models with possibly nonsmooth residuals [PDF]

This paper considers semiparametric efficient estimation of conditional moment models with possibly nonsmooth residuals in unknown parametric components (Θ) and unknown functions (h)of endogenous variables.
