Confidence Intervals for the Long-Term Noise Indicators Using the Kernel Density Estimator

Archives of Acoustics, 2016
A non-classical model of interval estimation based on the kernel density estimator is presented in this paper. This model has been compared with interval estimation algorithms of the classical (parametric) statistics assuming that the standard deviation ...

INTERVAL ESTIMATION OF THE VOLUMES OF RESOURCE CONSUMPTION AT THE STOCHASTIC BASIC DATA

Вестник университета, 2018
The method of interval estimation of resource consumption volumes is considered with the random nature of a multitude of random factors. The necessity of taking into account errors in the values of functions and arguments when estimating the parameters ...

Interval estimation of trigonometrical splines [PDF]

MATEC Web of Conferences, 2019
Quite often, it is necessary to quickly determine variation range of the function. If the function values are known at some points, then it is easy to construct the local spline approximation of this function and use the interval analysis rules.

Minimum scoring rule inference [PDF]

, 2014
Proper scoring rules are methods for encouraging honest assessment of probability distributions. Just like likelihood, a proper scoring rule can be applied to supply an unbiased estimating equation for any statistical model, and the theory of such ...

Reduced-Order and Full-Order Interval Observers Design for Discrete-Time System

IEEE Access, 2020
In this paper, the design of reduced-order and full-order interval observers for discrete-time system is investigated. First, the original system is transformed into a descriptor system with the ability to estimate the unknown noise of sensors.
