Estimating the Conditional Density in Scalar-On-Function Regression Structure: k-N-N Local Linear Approach

open access: yesMathematics, 2022
In this study, the problem of conditional density estimation of a scalar response variable, given a functional covariable, is considered. A new estimator is proposed by combining the k-nearest neighbors (k-N-N) procedure with the local linear approach ...

Kernel Conditional Density Operators

open access: yesCoRR, 2019
We introduce a novel conditional density estimation model termed the conditional density operator (CDO). It naturally captures multivariate, multimodal output densities and shows performance that is competitive with recent neural conditional density models and Gaussian processes.

Strong Uniform Consistency Rates of Conditional Density Estimation in the Single Functional Index Model for Functional Data Under Random Censorship

open access: yesRevstat Statistical Journal, 2022
The main objective of this paper is to investigate the estimation of conditional density function based on the single-index model in the censorship model when the sample is considered as an independent and identically distributed (i.i.d.) random ...

Investigation the Joint Probabilistic Behavior of River Flow Discharge-Suspended Sediment Load in Nazlochai Basin, Urmia [PDF]

open access: yesWater Harvesting Research
Accurately determining the relationship between river flow discharge and suspended sediment load in watersheds is challenging due to the influence of natural and human-induced variables on river estimations.

CONDITIONAL DENSITY MODELS FOR ASSET PRICING [PDF]

open access: yesInternational Journal of Theoretical and Applied Finance, 2010
We model the dynamics of asset prices and associated derivatives by consideration of the dynamics of the conditional probability density process for the value of an asset at some specified time in the future. In the case where the price process is driven by Brownian motion, an associated "master equation" for the dynamics of the conditional ...

Improved parameter estimators for the flexible extended skew-t model with extensive simulations, applications and volatility modeling

open access: yesScientific African, 2023
This study introduces a new conditional innovation density called the generalized odd generalized exponentiated skew-t (GOGEST) distribution for the generalized autoregressive conditional heteroscedasticity (GARCH) volatility models.

Bottleneck Conditional Density Estimation

open access: yesCoRR, 2016
We introduce a new framework for training deep generative models for high-dimensional conditional density estimation. The Bottleneck Conditional Density Estimator (BCDE) is a variant of the conditional variational autoencoder (CVAE) that employs layer(s) of stochastic variables as the bottleneck between the input $x$ and target $y$, where both are high-

Nonparametric Estimation of the Density Function of the Distribution of the Noise in CHARN Models

open access: yesMathematics, 2022
This work is concerned with multivariate conditional heteroscedastic autoregressive nonlinear (CHARN) models with an unknown conditional mean function, conditional variance matrix function and density function of the distribution of noise.
