Estimation of a distribution function using Lagrange polynomials with Tchebychev-Gauss points
Pages: 399 – 410
The estimation of the distribution function of a real random variable is an intrinsic topic in non parametric estimation. To this end, a distribution estimator based on Lagrange polynomials and Tchebychev–Gauss points, is introduced. Some asymptotic properties of the proposed estimator are investigated, such as its asymptotic bias, variance, mean squared error and Chung–Smirnov propriety. The asymptotic normality and the uniform convergence of the estimator are also established. Lastly, the performance of the proposed estimator is explored through a certain simulation examples.
