Researchers have developed a new nonparametric model using Bernstein polynomials to approximate isotropic covariance functions in infinite-dimensional spaces. This method, termed sieve maximum likelihood (sML) estimation, offers a computationally efficient way to estimate these functions. Numerical comparisons indicate that the sML estimator outperforms existing parametric and nonparametric methods in reducing bias and achieving lower error norms, with a practical application demonstrated on precipitation data.
