Least Squares Two-Point Function Estimation
arXiv:1808.05552 · doi:10.3847/2515-5172/aad9a7
Abstract
The standard estimator for the two-point function of a homogeneous and isotropic random field is a special case of a larger class of least squares estimators that interpolate the function values. Using a different interpolation scheme, two-point function values can be estimated at specific distances, instead of the binned averages.
