Bounds on Spreads of Matrices related to Fourth Central Moment. II
R. Sharma, R. Kumar, R. Saini +1
We derive some inequalities involving first four central moments of discrete and continuous distributions. Bounds for the eigenvalues and spread of a matrix are obtained when all i…

Complementary upper bounds for fourth central moment with extensions and applications
R. Sharma, R. Kumar, R. Saini +1
We prove some inequalities involving fourth central moment of a random variable that takes values in a given finite interval. Both discrete and continuous cases are considered. Bou…
