Two-sided total variation estimate for centered Gamma approximation in the second Wiener chaos
Let ν>0\nu>0ν>0, and let F=I2(f)F=I_2(f)F=I2(f) belong to the second Wiener chaos with … Let G(ν)∼CenteredGamma(ν)G(\nu)\sim\operatorname{CenteredGamma}(\nu)G(ν)∼CenteredGamma(ν). Two-sided total variation conjecture. There exist consta…
