Hyers-Ulam Stability of Lagrange’s Mean Value Points in Two Variables [PDF]
Mathematics, 2018 Using a theorem of Ulam and Hyers, we will prove the Hyers-Ulam stability of two-dimensional Lagrange’s mean value points ( η , ξ ) which satisfy the equation, f ( u , v ) − f ( p , q ) = ( u − p ) f x ( η , ξ ) + ( v − q ) f y ( η , ξ ) , where ( p , q ) and ( u , v ) are distinct points in the plane ...

Characterizations of the equality of two-variable generalized quasiarithmetic means
Journal of Mathematical Analysis and Applications, 2022 This paper is motivated by an astonishing result of H. Alzer and S. Ruscheweyh published in 2001 in the Proc. Amer. Math. Soc., which states that the intersection of the classes two-variable Gini means and Stolarsky means is equal to the class of two-variable power means.

Comparisons of mandatory and discretionary lane changing behavior on freeways
International Journal of Transportation Science and Technology, 2018 This research performs comparative analyses on drivers’ behavior during mandatory and discretionary lane changes. We do this by examining the statistical properties of four lane changing decision variables that describe the gaps between the subject ...

On the invariance equation for two-variable weighted nonsymmetric Bajraktarević means [PDF]
Aequationes mathematicae, 2018 The purpose of this paper is to investigate the invariance of the arithmetic mean with respect to two weighted Bajraktarević means, i.e., to solve the functional equation $$ \bigg(\frac{f}{g}\bigg)^{\!\!-1}\!\!\bigg(\frac{tf(x)+sf(y)}{tg(x)+sg(y)}\bigg) +\bigg(\frac{h}{k}\bigg)^{\!\!-1}\!\!\bigg(\frac{sh(x)+th(y)}{sk(x)+tk(y)}\bigg)=x+y \qquad(x,y\in I)

On a functional equation related to two-variable Cauchy means [PDF]
Mathematical Inequalities & Applications, 2019 In this paper, we are dealing with the solution of the functional equation $$ φ\Big(\frac{x+y}2\Big)(f(x)-f(y))=F(x)-F(y), $$ concerning the unknown functions $φ,f$ and $F$ defined on a same open subinterval of the reals. Improving the previous results related to this topic, we describe the solution triplets $(φ,f,F)$ assuming only the continuity of $φ$

International Journal of Mathematics and Mathematical Sciences, 2005 The notion of invariance under transformations (changes of coordinates) of the Cauchy mean-value expression is introduced and then used in furnishing a suitable two-variable version of a result by L. Losonczi on equality of many-variable Cauchy means. An

Application of student's t-test, analysis of variance, and covariance
Annals of Cardiac Anaesthesia, 2019 Student's t test (t test), analysis of variance (ANOVA), and analysis of covariance (ANCOVA) are statistical methods used in the testing of hypothesis for comparison of means between the groups.

New inequalities for means in two variables [PDF]
Mathematical Inequalities & Applications, 2008 In this paper, some bounds for I(x, y) in terms of A(x, y) and L(x, y) , and L(x, y) in terms of G(x, y) and I(x, y) are established. Mathematics subject classification (2000): 26E60, 26D07.

Computer aided solution of the invariance equation for two-variable Stolarsky means [PDF]
Applied Mathematics and Computation, 2010 We solve the so-called invariance equation in the class of two-variable Stolarsky means ${S_{p,q}:p,q\in\R}$, i.e., we find necessary and sufficient conditions on the 6 parameters $a,b,c,d,p,q$ such that the identity [S_{p,q}\big(S_{a,b}(x,y),S_{c,d}(x,y)\big)=S_{p,q}(x,y) \qquad (x,y \in \R_+)] be valid.
