The Bias and Accuracy of Moment Estimators

Biometrika, 1970
SUMMARY A new method for finding the biases and covariances of moment estimators to order n-2 is outlined and compared with existing solutions. It is thought that the new approach is likely to be particularly useful for cases where moment estimation is complicated.

Moments estimation in Radon space

Pattern Recognition Letters, 1994
Summary: We show a method of obtaining general and orthogonal moments, specifically Legendre and Zernike moments, from the Radon Transform data of a two-dimensional function. The regular or geometric moments are first evaluated directly from the projection data and the orthogonal moments are derived from these regular moments.

Moment Estimators and Maximum Likelihood

Biometrika, 1958
where J'q2(x) P(x; 0) dx = Or, J'q(x) qq(x) P(x; 0) dx = 0 (r+ s). (2) To avoid undue complication at this stage we assume P(x; 0) is continuous throughout its range. We reconsider the restrictions on P in a subsequent section.
