The correlation coefficient between stocks depends on price history and
includes information on hierarchical structure in financial markets. It is
useful for portfolio selection and estimation of ri...
Variational Calculation of Low-energy Positron Life Time in Xe Atoms
Positron Annihilation Bound wavefunction Scattered wavefunction Variational Method
2010/6/30
The least-squares variational method (LSVM) is used for determining trial wavefunctions representing lowenergy positron-xenon elastic scattering, which are used to determine the positron lifetime. The...
