Thank you for having patience with my silly question. In my problem, the real "r" was in fact Cosh[x] with x real, which is always >=1 which I neglected to consider. I was asleep at the wheel, and your example woke me up. Thank you. MMA still will... |

Good, I learned something... Thanks. |

Isn't KL Divergence Total[p Log[p/q]], not Total[p Log[p]/Log[q]] ? |

Hi Ilian - The real problem I have is somewhat less complicated. I have an unstructured {xa,ya} and I want to calculate the corresponding {x,y} which is structured; it has equal increments in x and y. That means I can use Interpolation[ ] to... |

I have tried to narrow things down. The E^((I \[Pi])/\a) term does not make things complex, necessarily. My problem boils down to Assuming[k > 0 && a > 0 && y > 1/a, FullSimplify[Exp[I \[Pi]/a] (-1 + a y)^(1/a) == (1 - a y)^(1/a)]] yields True,... |
