Comparison of the efficiency of some Non-Parametric Methods in estimating Multivariate Linear Regression Models [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2013
Regression is one of the statistical methods and widely used in various fields of science in terms of defining clearly the relationship between the variables in the form of an equation to estimate the parameters and the strength and direction of this ...

New extension of beta, Gauss and confluent hypergeometric functions

open access: yesCumhuriyet Science Journal, 2021
There are many extensions and generalizations of Gamma and Beta functions in the literature. However, a new extension of the extended Beta function B_(ζ〖, α〗_1)^(α_2;〖 m〗_1,〖 m〗_2 ) (a_1,a_2 ) was introduced and presented here because of its important ...

Absolute moments of the variance-gamma distribution [PDF]

open access: yes
We obtain exact formulas for the absolute raw and central moments of the variance-gamma distribution, as infinite series involving the modified Bessel function of the second kind and the modified Lommel function of the first kind.

Efficient pricing of barrier options with the variance-gamma model

open access: yes, 2004
We develop an efficient Monte Carlo algorithm for pricing barrier options with the variance gamma model [fMAD98a]. After generalizing the double-gamma bridge sampling algorithm of [fAVR03a], we develop conditional bounds on the process paths and exploit ...

Cumulant-Based Goodness-of-Fit Tests for the Tweedie, Bar-Lev and Enis Class of Distributions

open access: yesMathematics, 2023
The class of natural exponential families (NEFs) of distributions having power variance functions (NEF-PVFs) is huge (uncountable), with enormous applications in various fields.

Robustness of analysis of covariance (ancova) under the distributions assumptions and variance homogeneity [PDF]

open access: yesEurasian Journal of Veterinary Sciences, 2020
Aim: As in all parametric methods, the ANCOVA method assumes that normal distributions of errors, homogeneity of variances, and error terms are independent of each other. However, unusual distributions in practice are more common than normal distribution.

Bayesian Approach for Confidence Intervals of Variance on the Normal Distribution

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2022
This research aims to compare estimating the confidence intervals of variance based on the normal distribution with the primary method and the Bayesian approach. The maximum likelihood is the well-known method to approximate variance, and the Chi-squared

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
