Marshall's lemma for convex density estimation

, 2007
Marshall's [Nonparametric Techniques in Statistical Inference (1970) 174--176] lemma is an analytical result which implies $\sqrt{n}$--consistency of the distribution function corresponding to the Grenander [Skand. Aktuarietidskr.

Saddlepoint approximations for likelihood ratio like statistics with applications to permutation tests

, 2012
We obtain two theorems extending the use of a saddlepoint approximation to multiparameter problems for likelihood ratio-like statistics which allow their use in permutation and rank tests and could be used in bootstrap approximations.

Highly adaptive Lasso for estimation of heterogeneous treatment effects and treatment recommendation

Journal of Causal Inference
The estimation of conditional average treatment effects (CATEs) is an important problem in many applications. Many machine learning-based frameworks for such estimation have been proposed, including meta-learning, causal trees, and causal forests ...

Targeted maximum likelihood based estimation for longitudinal mediation analysis

Journal of Causal Inference
Causal mediation analysis with random interventions has become an area of significant interest for understanding time-varying effects with longitudinal and survival outcomes.

A statistical Framework for a new two-parameter unit Bilal distribution with application to model Asymmetric Data

Heliyon
In the realm of statistical mechanics, unit models are commonly employed to elucidate tangible numerical values that fall within the range of 0–1, encompassing entities like proportions, percentages, and probabilities.

Local polynomial regression for circular predictors

, 2009
We consider local smoothing of datasets where the design space is the d-dimensional (d >= 1) torus and the response variable is real-valued. Our purpose is to extend least squares local polynomial fitting to this situation.

On the exponential inequality for acceptable random variables

Journal of Inequalities and Applications, 2011
In this paper, we obtain some new exponential inequalities for partial sums and their finite maximum of acceptable random variables by the results of Sung et al. (J. Korean Stat. Soc., 40, 109-114, 2011) and in different ways from theirs.
