1. Univariate density estimation by orthogonal series
2. Burg J. P.(1975).Maximum Entropy Spectral Analysis. Ph.D. dissertation Dept. of Geophysics Stanford University. (Suggests the method now known as the maximum entropy method for estimating spectral densities. Burg's idea was first set forth in a paper entitled “Maximum entropy power spectral analysis ” presented at the 37th Annual Int. SEG Meeting Oklahoma City OK Oct. 31 1967. It is closely related to Parzen.)
