Analysis and Allocation of Cancer-Related Genes Using Vague DNA Sequence Data

open access: yesFrontiers in Genetics, 2022
To test the equality of several independent multinomial distributions, the chi-square test for count data is applied. The existing test can be applied when complete information about the data is available.

Chi-square, Student and Fisher-Snedecor Statistical Distributions and Their Application

open access: yesСтатистика України, 2018
The Chi-square distribution is the distribution of the sum of squared standard normal deviates. The degree of freedom of the distribution is equal to the number of standard normal deviates being summed. For the first time this distribution was studied by

A Minimum Logit Chi-Squared Estimator for Asymmetric Generalizations of the Logistic Model [PDF]

open access: yesThe Egyptian Statistical Journal, 1993
The minimum logit chi-squared estimator, as originally proposed by Berkson (1944, 1955), has been suggested for use in estimating the parameters in a linear logistic regression model for binomial response data. It is asymptotically normal when the number

Extremes of independent chi-square random vectors [PDF]

open access: yes, 2010
We prove that the componentwise maximum of an i.i.d. triangular array of chi-square random vectors converges in distribution, under appropriate assumptions on the dependence within the vectors and after normalization, to the max-stable Husler-Reiss ...

The γ-order generalized chi-square distribution

open access: yesResearch in Statistics
Based on the definition of the γ-order generalized normal, the γ-order generalized standard normal is obtained, and applications are referred. We proceed on the definition of the γ-order generalized chi-square, [Formula: see text] and the probability ...

Blind Additive Gaussian White Noise Level Estimation from a Single Image by Employing Chi-Square Distribution

open access: yesEntropy, 2022
The additive Gaussian white noise (AGWN) level in real-life images is usually unknown, for which the empirical setting will make the denoising methods over-smooth fine structures or remove noise incompletely.

The bivariate noncentral chi-square distribution – A compound distribution approach

open access: yes, 2011
This paper proposes the bivariate noncentral chi-square (BNC) distribution by compounding the Poisson probabilities with the bivariate central chi-square distribution.

Chebyshev–Edgeworth-Type Approximations for Statistics Based on Samples with Random Sizes

open access: yesMathematics, 2021
Second-order Chebyshev–Edgeworth expansions are derived for various statistics from samples with random sample sizes, where the asymptotic laws are scale mixtures of the standard normal or chi-square distributions with scale mixing gamma or inverse ...

Continuity correction of Pearson’s chi-square test in 2x2 Contingency Tables: A mini-review on recent development

open access: yesEpidemiology, Biostatistics and Public Health, 2019
The Pearson’s chi-square test represents a nonparametric test more used in Biomedicine and Social Sciences, but it introduces an error for 2x2 contingency tables, when a discrete probability distribution is approximated with a continuous distribution ...
