Cubic Unbiased Estimator: Some Properties

Abstract

Unbiasedness of estimator, which had originally been defined with the help of arithmetic expectation and was defined later with the help of geometric expectation, harmonic expectation & quadratic expectation, has here been defined based on cubic expectation and termed as cubic unbiased estimator. Concept of cubic unbiased estimator, with some of its properties, has been discussed in this article.
