Wind Power Interval Forecasting Based on Confidence Interval Optimization

open access: yesEnergies, 2018
Most of the current wind power interval forecast methods are based on the assumption the point forecast error is subject to a known distribution (such as a normal distribution, beta distribution, etc.).

Establishment of Reference Interval of Serum Prolactin in an Indian Population [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2014
Background: Reference data on serum prolactin levels based on a representative Indian sample are still lacking. The western normative laboratory values used for clinical diagnosis may not be applicable to Indian population. The objective of the study

Confidence Intervals for Stochastic Arithmetic [PDF]

open access: yesACM Transactions on Mathematical Software, 2021
Quantifying errors and losses due to the use of Floating-point (FP) calculations in industrial scientific computing codes is an important part of the Verification, Validation, and Uncertainty Quantification process. Stochastic Arithmetic is one way to model and estimate FP losses of accuracy, which scales well to large, industrial codes.

Confidence interval how sure you are?

open access: yesJournal of Applied Hematology, 2014
Previously, researchers were reported P value as a basis for conclusion, but in this era of evidence-based medicine we are interested now about the precision of the results obtained that allow us to make right decisions in health care practice.

A New Exact Confidence Interval for the Difference of Two Binomial Proportions

open access: yesRevstat Statistical Journal, 2020
We consider interval estimation of the difference between two binomial proportions. Several methds of constructing such an interval are known. Unfortunately those confidence intervals have poor coverage probability: it is significantly smaller than the ...

Multivariate Confidence Intervals [PDF]

open access: yes, 2017
Confidence intervals are a popular way to visualize and analyze data distributions. Unlike p-values, they can convey information both about statistical significance as well as effect size. However, very little work exists on applying confidence intervals to multivariate data.

The Shortest Clopper–Pearson Randomized Confidence Interval for Binomial Probability

open access: yesRevstat Statistical Journal, 2017
Zieli´nski (2010) showed the existence of the shortest Clopper–Pearson confidence interval for binomial probability. The method of obtaining such an interval was presented as well. Unfortunately, the confidence interval obtained has one disadvantage: it

Interval-Valued Intuitionistic Fuzzy Confidence Intervals

open access: yesJournal of Intelligent Systems, 2019
Confidence intervals are useful tools for statistical decision-making purposes. In case of incomplete and vague data, fuzzy confidence intervals can be used for decision making under uncertainty.

Validation of models with constant bias: an applied approach [PDF]

open access: yesRevista Mvz Cordoba, 2014
Objective. This paper presents extensions to the statistical validation method based on the procedure of Freese when a model shows constant bias (CB) in its predictions and illustrate the method with data from a new mechanistic model that predict weight ...
