A class of goodness-of-fit statistics including that of Freeman and Tukey for testing discrete models is introduced; optimum statistics are identified through comparison of asymptotic moments with those of power divergence statistics and via simulations. Further new classes of test statistics are...

It is not an overstatement to say that statistics is based on various transformations of data. Basic statistical summaries such as the sample mean, variance, z-scores, histograms, etc., are all transformed data. Some more advanced summaries, such as principal components, periodograms, empirical...

In this paper a new wavelet shrinkage technique is proposed and investigated. When data consist of a multiplicity of related noisy signals, we propose a wavelet-based shrinkage estimation procedure to summarize all data components into a single regularized and representative signal...
