Asymptotics for penalized additive B-spline regression [PDF]

, 2011
This paper is concerned with asymptotic theory for penalized spline estimator in bivariate additive model. The focus of this paper is put upon the penalized spline estimator obtained by the backfitting algorithm.

An improved estimator for non-Gaussianity in cosmic microwave background observations [PDF]

, 2012
An improved estimator for the amplitude fnl of local-type non-Gaussianity from the cosmic microwave background (CMB) bispectrum is discussed. The standard estimator is constructed to be optimal in the zero-signal (i.e., Gaussian) limit.

Empirical likelihood estimation of the spatial quantile regression [PDF]

, 2012
The spatial quantile regression model is a useful and flexible model for analysis of empirical problems with spatial dimension. This paper introduces an alternative estimator for this model.

Convex Banding of the Covariance Matrix [PDF]

, 2014
We introduce a new sparse estimator of the covariance matrix for high-dimensional models in which the variables have a known ordering. Our estimator, which is the solution to a convex optimization problem, is equivalently expressed as an estimator which ...

A consistent estimator for the binomial distribution in the presence of "incidental parameters": an application to patent data [PDF]

, 2003
In this paper a consistent estimator for the Binomial distribution in the presence of incidental parameters, or fixed effects, when the underlying probability is a logistic function is derived.

Confidence intervals in regression centred on the SCAD estimator

, 2012
Consider a linear regression model. Fan and Li (2001) describe the smoothly clipped absolute deviation (SCAD) point estimator of the regression parameter vector.

Nonparametric Estimation of an Additive Model With a Link Function [PDF]

, 2004
This paper describes an estimator of the additive components of a nonparametric additive model with a known link function. When the additive components are twice continuously differentiable, the estimator is asymptotically normally distributed with a ...

Stochastic Restricted Biased Estimators in misspecified regression model with incomplete prior information

, 2018
In this article, the analysis of misspecification was extended to the recently introduced stochastic restricted biased estimators when multicollinearity exists among the explanatory variables.

Estimation of a discrete monotone distribution [PDF]

, 2009
We study and compare three estimators of a discrete monotone distribution: (a) the (raw) empirical estimator; (b) the "method of rearrangements" estimator; and (c) the maximum likelihood estimator.
