Multiwavelet density estimation for biased data

Communications in Statistics - Simulation and Computation, 2019
In this article, we present our method for multiwavelet estimation for a density function based on random samples from a weighted distribution.

Visual Biases in Estimating Body Size

2018
Western populations have been getting progressively heavier and the prevalence of obesity in the general population has become a major public health problem. A potential contributory factor in the rise of obesity is the inability to accurately detect weight increase using visual cues. This is a problem not only for members of the public whose weight is

Accurate localization using biased estimation

2010 Sixth International Conference on Natural Computation, 2010
Localization of mobile stations(MS) is of considerable interest in wireless communication. In this paper, three algorithms are developed for accurate mobile location using the time-of-arrival measurements. The first algorithm is an unconstrained least square estimator(LSE) which has implementation simplicity. Our methods referring linear bias estimator(

Biased estimation of a variance

Journal of the Italian Statistical Society, 1996
Summary: Let \(S^2 (\alpha) = \frac{1}{n + \alpha }\sum _{\text I = 1}^n ( {X_i - \hat \mu })^2\), where \(X _{i}\) are i.i.d. random variables with a finite variance \(\sigma ^{2}\) and \(\hat{\mu}\) is the usual estimate of the mean of \(X _{i}\). We consider the problem of finding optimal \(\alpha \) with respect to the minimization of the expected ...

On the biased estimation of nonlocal means filter

2008 IEEE International Conference on Multimedia and Expo, 2008
The recent nonlocal means filter (NLM) exhibits exciting performance for image or video denoising. However, the estimation of NLM is biased and tends to keep the value of noise. In the process of NLM, the target pixel (the pixel being processed) is involved in patch distance measuring, which, in turn, controls the restoration of the target pixel.

ESTIMATION FROM A LENGTH-BIASED DISTRIBUTION

Statistics & Risk Modeling, 1985
Let \(F_ n(t)\) be the non-parametric MLE of a life time distribution F on the basis of a sample of size n from the length biased distribution of F. If \(G(t)=\mu^{-1}\int^{t}_{0}x dF(x)\) and \(G_ n(t)\) denotes the empirical df then \[ F_ n(t)=\int^{t}_{0}y^{-1}dG_ n(y)/\int^{\infty}_{0}y^{-1}dG_ n(y). \] On the assumption that G is continuous on (0,\
