A Method of Probability Distribution Modeling of Multi-Dimensional Conditions for Wind Power Forecast Error Based on MNSGA-II-Kmeans

Energies, 2022
How to consider both the influence of weather and wind power in the modeling process of probability distribution of wind power forecast error (WPFE), and to emphasize the application value of conditional modeling, is rarely studied at present. This paper

The Application of a Joint Distribution of Significant Wave Heights and Peak Wave Periods in the Northwestern South China Sea

Journal of Marine Science and Engineering
A joint distribution of significant wave heights (Hs) and peak wave periods (Tp) in the northwestern South China Sea is created using a conditional distribution model in this work.

Sampling the Multivariate Standard Normal Distribution under a Weighted Sum Constraint

Risks, 2018
Statistical modeling techniques—and factor models in particular—are extensively used in practice, especially in the insurance and finance industry, where many risks have to be accounted for.

Asymptotic Results of Some Conditional Nonparametric Functional Parameters in High-Dimensional Associated Data

Mathematics, 2023
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 ...

What to Choose? The Value of Label Claims to Fresh Produce Consumers

Journal of Agricultural and Resource Economics, 2008
We examine consumer response to label information using a hypothetical choice experiment on red leaf lettuce attribute bundles. Using survey responses, several mixed logit models with random parameters and varying correlation assumptions are estimated ...

On the Estimation for Compound Poisson Inarch Processes

Revstat Statistical Journal, 2021
Considering the wide class of discrete Compound Poisson INARCH models, introduced in [6], the main goal of this paper is to develop and compare parametric estimation procedures for first-order models, applicable without specifying the conditional ...

Optimal Bayesian Estimation of a Regression Curve, a Conditional Density, and a Conditional Distribution

Mathematics, 2022
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.

Crop Yield Skewness and the Normal Distribution

Journal of Agricultural and Resource Economics, 2009
Empirical studies point to negative crop yield skewness, but the literature provides few clear insights as to why. This paper formalizes three points on the matter. Statistical laws on aggregates do not imply a normal distribution.

Further characterization based on conditional expectations: new and extended findings

Journal of Taibah University for Science, 2023
On the basis of conditional expectation of a random variable function, we present few characterization findings in this study. For a given function g, [Formula: see text], we present necessary and sufficient conditions for characterization results in ...
