# scipy.special.owens_t

scipy.special.owens_t(h, a) = <ufunc 'owens_t'>

  Owen’s T Function.

  The function T(h, a) gives the probability of the event (X > h and 0 < Y < a * X) where X and Y are independent standard normal random variables.

  Parameters
    h: array_like

      Input value.

    a: array_like

      Input value.

  Returns
    t: scalar or ndarray

      Probability of the event (X > h and 0 < Y < a * X), where X and Y are independent standard normal random variables.
