On the Regression Model for Generalized Normal Distributions

open access: yesEntropy, 2021
The traditional linear regression model that assumes normal residuals is applied extensively in engineering and science. However, the normality assumption of the model residuals is often ineffective.

The characterisation of the normal distribution [PDF]

open access: yesJournal of the Australian Mathematical Society, 1960
There are a number of well known theorems on the mutual independence of forms, either linear or quadratic, in normal variables. Some of these theorems can only hold when the system of variables is normal or degenerate and so the possibility of certain forms being independent characterises the normal distribution.

Stochastic Orders on the Univariate Unified Skew Normal Family of Distributions

open access: yesRevstat Statistical Journal
The family of Unified Skew Normal distributions is associated with probability distributions encountered in various problems, notably those of the selection of individuals in a normal population.

Enhancing the Performance of the Mont Carlo Simulation for Generating Correlated Data: An Application to Climate Change [PDF]

open access: yesمهندسی منابع آب, 2016
The Mont Carlo simulation is widely used for data generation based on specified distribution. However, generation of correlated data is only possible for specific distributions (bivariate normal), while it is required to deal with non-normal ...

Assessing the measurement uncertainty of qualitative analysis in the clinical laboratory

open access: yesJournal of Laboratory Medicine, 2020
Measurement uncertainty is a parameter that is associated with the dispersion of measurements. Assessment of the measurement uncertainty is recommended in qualitative analyses in clinical laboratories; however, the measurement uncertainty of qualitative ...

One-sided tolerance limits for the normal distribution, p = 0.80, ? = 0.80

open access: yes, 1976
A table is given of factors k used in constructing one-sided tolerance limits for a normal distribution. This table was obtained by interpolation in an existing table of percentage points of the noncentral t-distribution.

Mixed Size-Biased Log-Normal Distribution with Truncated Normal Prior and Its Application in Insurance Ratemaking

open access: yesRisks
In the insurance literature, accurately predicting extreme losses has been a persistent and important problem. Recently, under the modelling framework of weighted distributions, several finite-mixture size-biased distributions, including size-biased ...

Deformed Normal Distributions

open access: yesESAIM: Probability and Statistics
It is well known that the probability distribution of the product of two normal variables itself approaches a normal distribution if one of the factor variables has a low coefficient of variation. A related, but apparently somewhat neglected problem, is to find the conditional distribution of a factor variable when the product of two independent normal

The Issue of Selection of Appropriate Methodology and Methods of Graphical Representation of Data in Biomedical Research

open access: yesStudies in Logic, Grammar and Rhetoric, 2023
The development of medicine is based on reliable medical research. This is a process that must be planned in detail and performed in accordance with the accepted study protocol, as any negligence – even a small one – or deviation from the protocol may ...

A Property of the Normal Distribution

open access: yesThe Annals of Mathematical Statistics, 1954
The following theorem is proved. Let $X_1, X_2, \cdots, X_n$ be $n$ independently (but not necessarily identically) distributed random variables, and assume that the $n$th moment of each $X_i(i = 1, 2, \cdots, n)$ exists. The necessary and sufficient conditions for the existence of two statistically independent linear forms $Y_1 = \sum^n_{s=1} a_sX_s ...
