This study introduces a new estimator for the power of moments (θ) of a random variable X. The proposed estimator is shown to be consistent under general conditions, offering a reliable method for statistical estimation.
Area of Science:
- Statistics
- Probability Theory
Background:
- Estimating moments of random variables is crucial in statistical analysis.
- The power of moments (θ) is a key parameter characterizing a distribution's behavior.
Purpose of the Study:
- To propose a novel, simple point estimator for the power of moments (θ).
- To investigate the asymptotic properties of the proposed estimator.
- To establish the consistency of the estimator under general conditions.
Main Methods:
- A random sample of size n is drawn from the distribution of X.
- A simple point estimator for θ is constructed using the sample data.
- Asymptotic properties, including consistency, are mathematically derived.
Main Results:
- The proposed estimator for θ is derived.
- Mathematical proofs demonstrate that the estimator converges to the true value of θ.
- The estimator is proven to be consistent under broad conditions.
Conclusions:
- The developed point estimator for the power of moments (θ) is statistically consistent.
- This provides a robust tool for estimating distribution characteristics.
- The findings are applicable to various statistical modeling scenarios.

Moment of Inertia
If a rigid body is rotating about an axis but is not in translational motion, its translational kinetic energy is zero. However, since each particle undergoes rotational motion, it possesses non-zero velocity and kinetic energy. Thus, the kinetic energy of the rigid body, which is the sum of the...
