. First, we establish a new representation for the central chi-square density based on sums of powers of generalized Gaussian …, robust and efficient acceptance–rejection method for generalized Gaussian sampling and thus central chi-square sampling …. Third, we derive a simple, high-accuracy, robust and efficient direct inversion method for generalized Gaussian sampling …
