Chen, X. R.; Krishnaiah, P. R.; Liang, W. W. - In: Journal of Multivariate Analysis 31 (1989) 2, pp. 178-186
In this paper, the authors studied certain properties of the estimate of Liang and Krishnaiah (1985, J. Multivariate Anal. 16, 162-172) for multivariate binary density. An alternative shrinkage estimate is also obtained. The above results are generalized to general orthonormal systems.
