Kr is supposed to be used to study the properties of the windowless gaseous tritium source of the experiment KATRIN. In this work we deduce the amount of Kr which is necessary to determine possible potential inhomogeneities via conversion-electron-line broadening. PACS: 29.30.Dn, 07.81.+a, 02.50.-r

Please provide the appropriate primary and secondary classifications from 5 We derive a test in order to examine the need of modeling su...
A testing problem of homogeneity in gamma mixture models is studied. It is found that there is a proportion of the penalized likelihood ratio test statistic that degenerates to zero. The limiting distribution of this statistic is found to be the chi-bar-square distributions. The degeneration is due to the negative-definiteness of a complicated random matrix, depending on the shape parameter und...
The aim of this paper is to discuss homogeneity testing of the exponential distribution. We introduce the exact likelihood ratio test of homogeneity in the subpopulation model, ELR, and the exact likelihood ratio test of homogeneity against the two-components subpopulation alternative, ELR2. The ELR test is asymptotically optimal in the Bahadur sense when the alternative consists of sampling fr...
A density ratio is defined by the ratio of two probability densities. We study the inference problem of density ratios and apply a semi-parametric density-ratio estimator to the two-sample homogeneity test. In the proposed test procedure, the f -divergence between two probability densities is estimated using a density-ratio estimator. The f -divergence estimator is then exploited for the two-sa...
