An illustration is again provided by the tent map copula, for which both tests of Genest et al.
To define the latter, we will proceed as in Genest et al. Next, assume that the following regularity conditions hold. Condition 1. Condition 2. The regularity conditions are the same as in Genest et al. Theorem 3.

In principle this result can be used to compute the asymptotic local power of the tests considered here. To do this in full generality is a much more complicated endeavour than in Genest et al. Example 1. The loss of power is, however, rather small. Table 6. The authors thank Dr Elaine de Guise for permission to use the brain injury data and for insightful discussions.

Of course, data jittering cannot be recommended for testing independence per se, as the added noise could decrease efficiency and will not lead to reproducible results in any case.

From Proposition 2 of Genest et al. As shown in Proposition 3 of Genest et al. By equation A.
Following Genest et al. This explains why in Table 5 , the tests based on the truncated statistics are significantly more powerful than the corresponding tests based on the nontruncated versions of these two classes of alternatives. For convenience, we provide a combined restatement of Theorem 1 and Corollary 1 from Genest et al. Proposition 8 in Genest et al. As shown in Proposition 2. From Proposition 6 in Genest et al.

Semiparametric segment M-estimation for locally stationary diffusions. The data are as follows:. The null hypothesis is that the average wind speed follows a CRD. We can use the one — sample t — test because the number of data is 30 and approximately normal distribution as to:.
The null hypothesis is that the average wind speed don't follow CRD.
The data consisting of 46 survival times in years for 46 patients are: 0. We test that the data follow the Compound Rayleigh model and found it is acceptable for these data.
The measures of the statistics indicate that the CR distribution is good fit to the real data. So, we conclude that the survival times in years of a group of patients follows CRD. This paper deals with constructing tables of critical values for some goodness of fit tests for Compound Rayleigh distribution based on empirical distribution functions.
Several goodness of fit tests are proposed and their powers are compared with some well-known goodness of fit tests based on empirical distribution function. The Kolmogorov-Smirnov and Cramer-von Misses type goodness of fit tests as well as Anderson Darling statistics for complete and censored data were proposed. These statistics were used to goodness of fit test for CR model. It is found that the introduced tests have good performance as compared with their competitor.
Distribution Theory for Tests Based on the Sample Distribution Function
In case of censored samples, it is noted —in general —that KS has the smallest power values among the two alternative distributions used Gamma and Chi-Square , while CVM has the largest power. However, when the exponential distributions used as an alternative, KS has the smallest power values while both CVM and AD are almost equivalent having the largest power values. Majdah M.

Abstract An important problem in statistics is to obtain information about the form of the population from which the sample is drawn. Introduction Compound Rayleigh distribution is one of the models which are useful in different areas of statistics. Methods 2.
Critical values for the test statistics In this section, we will create tables of critical values for the KS, CVM and AD test statistics in case of complete and censored samples if the probability distribution is Compound Rayleigh. H1 The distribution of the censored sample is not Compound Rayleigh distribution. Open in a separate window. Analysis 3. Power comparison The power of a goodness of fit test is defined as the probability that a statistic will lead to the rejection of the null hypothesis, H 0 , when it is false.
The alternative distributions are listed below: Methodology 4. Real data examples In this section, we applied our proposed proceeds to real data sets for illustration purpose. The data set is provided in the following: 0.
