In this paper, several related estimation problems are addressed from a Bayesian point of view, and optimal estimators are obtained for each of them when some natural loss functions are considered.

BackgroundIn drug trials, adverse events (AEs) burden can induce treatment non-adherence or discontinuation. The non-adherence and discontinuation induce selection bias, affecting drug safety interpretation.

The main objective of this work is to estimate, semi-parametrically, the mode of a conditional density when the response is a real valued random variable subject to censored phenomenon and the predictor takes values in a semi-metric space. We assume that

The convexity condition of density-functional theory
It has long been postulated that within density-functional theory (DFT), the total energy of a finite electronic system is convex with respect to electron count so that 2Ev[N0] ≤ Ev[N0 − 1] + Ev[N0 + 1]. Using the infinite-separation-limit technique, this Communication proves the convexity condition for any formulation of DFT that is (1) exact for all ...

Distinguishing density and the Distinct Spheres Condition [PDF]
If a graph $G$ has distinguishing number 2, then there exists a partition of its vertex set into two parts, such that no nontrivial automorphism of $G$ fixes setwise the two parts. Such a partition is called a 2-distinguishing coloring of $G$, and the parts are called its color classes.

Using conditional kernel density estimation for wind power density forecasting [PDF]
Of the various renewable energy resources, wind power is widely recognized as one of the most promising. The management of wind farms and electricity systems can benefit greatly from the availability of estimates of the probability distribution of wind ...

In this paper, we propose to study the asymptotic properties of some conditional functional parameters, such as the distribution function, the density, and the hazard function, for an explanatory variable with values in a Hilbert space (infinite ...

Density Conditions for Panchromatic Colourings of Hypergraphs [PDF]
A panchromatic \(t\)-colouring of a hypergraph \( H =(V,E)\) is a \(t\)-colouring such that each edge has at least one vertex of each colour. Hypergraph \(H\) is panchromatically \(t\)-choosable (panchromatically \(t\)-list-colourable) if, whenever each vertex is given a list of \(t\) colours, the vertices can be panchromatically \(t\)-coloured by ...

ADAPTIVE BAYESIAN ESTIMATION OF CONDITIONAL DENSITIES [PDF]
We consider a nonparametric Bayesian model for conditional densities. The model is a finite mixture of normal distributions with covariate dependent multinomial logit mixing probabilities. A prior for the number of mixture components is specified on positive integers. The marginal distribution of covariates is not modeled.
