Classical estimation methods (least squares, the method of moments and maximum likelihood) work well in regular cases such as the exponential family, but outliers can have undue in1uence on these methods. We de3ne population trimmed L-moments (TL-moments) and corresponding sample TL-moments as robust generalisations of population and sample L-moments. TL-moments assign zero weight to extreme ob...
Description The package implements the statistical theory of L-moments including L-moment estimation, probability-weighted moment estimation, parameter estimation for numerous familiar and not-so-familiar distributions, and L-moment estimation for the same distributions from the parameters. L-moments are derived from the expectations of order statistics and are linear with respect to the probab...
The 4-parameter generalized lambda distribution (GLD) is a flexible distribution capable of mimicking the shapes of many distributions and data samples including those with heavy tails. The method of L-moments and the recently developed method of trimmed L-moments (TL-moments) are attractive techniques for parameter estimation for heavy-tailed distributions for which the Land TL-moments have be...
Neutron-deficient nuclei near the Z=82 closed shell exhibit the phenomenon of shape coexistence where the nucleus can take on oblate, prolate, and even spherical shapes at around the same excitation energy. The single-proton excitations in 187 Tl (with Z=81) can be used as a probe into the microscopic mechanisms behind this phenomenon. Previous studies of 187 Tl deduced the presence of coexisti...
In-beam γ-ray spectroscopic studies of superdeformed bands in the mass 190 region are discussed with emphasis on recent results for Tl nuclei. Among those results, superdeformation at the edge of the region (in (189)Tl) and the first measurement of a superdeformed quadrupole moment in an odd-Z nucleus ((191)Tl) is presented. The experiments were conducted with the Gammasphere array at the Lawre...
Abstract In this paper, we have obtained the exact expression and recurrence relations for single moments of order statistics arising from Sushila distribution. We also L-moments, TL-moments distribution used them to find L-moment TL-moment estimators parameters The are using method maximum likelihood. Further, by these likelihood (MLEs), MLEs measures reliability considered Monte Carlo simulat...
Ab initio Dirac-Fock calculations of PT-odd interactions in TlF are reported which employ large sets of kinetically balanced Gaussian basis functions. Revised estimates are reported of bounds on the value of the electric dipole moment of the proton, dp , the tensor-pseudotensor coupling constant, CT , and the Schiff moment of the Tl nucleus, Q, based on analysis of existing experimental data. [...
A search of neutrino magnetic moment was carried out at the Kuo-Sheng Nuclear Power Station at a distance of 28 m from the 2.9 GW reactor core. With a high purity germanium detector of mass 1.06 kg surrounded by scintillating NaI(Tl) and CsI(Tl) crystals as anti-Compton detectors, a detection threshold of 5 keV and a background level of 1 kg(-1) keV(-1) day(-1) at 12-60 keV were achieved. Based...
