Asymptotic relative efficiency.
Asymptotic Relative Efficiency ] was pleased to read "Promise in Nonparametrics" by Royeen and Seaver (March, ] 986). As the authors state, analysis of data by non parametric methods when the strong assumptions for parametric counterparts cannot be met provides the researcher with effective statistical procedures that may be more realistic and valid in a given situation. It is also interesting ...
متن کاملAsymptotic relative efficiency of estimators
For statistical estimation problems, it is typical and even desirable that more than one reasonable estimator can arise for consideration. One natural and time-honored approach for choosing an estimator is simply to compare the sample sizes at which the competing estimators meet a given standard of performance. This depends upon the chosen measure of performance and upon the particular populati...
متن کاملAsymptotic Relative Efficiency in Estimation
For statistical estimation problems, it is typical and even desirable that several reasonable estimators can arise for consideration. For example, the mean and median parameters of a symmetric distribution coincide, and so the sample mean and the sample median become competing estimators of the point of symmetry. Which is preferred? By what criteria shall we make a choice? One natural and time-...
متن کاملAsymptotic Relative Efficiency in Testing
Making a substantiated choice of the most efficient statistical test of several ones being at the disposal of the statistician is regarded as one of the basic problems of Statistics. This problem became especially important in the middle of XX century when appeared computationally simple but ”inefficient” rank tests. Asymptotic relative efficiency (ARE) is a notion which enables to implement in...
متن کاملDistance measures and asymptotic relative efficiency
The relationship between distance measures and asymptotic relative efficiency is discussed. It is shown that the ratio of the Bhattacharyya distance or J divergences of two test statistics is equivalent to asymptotic relative efficiency. Two-input systems are discussed as examples, and the performances of the polarity coincidence correlator (PCC) and the correlator are discussed in terms of the...
