# scipy.special.log_ndtr

scipy.special.log_ndtr(x) = <ufunc 'log_ndtr'>

  Logarithm of Gaussian cumulative distribution function.

  Returns the log of the area under the standard Gaussian probability density function, integrated from minus infinity to x:

      log(1/sqrt(2*pi) * integral(exp(-t**2 / 2), t=-inf..x))

  Parameters
    x array_like, real or complex

      Argument

  Returns
    ndarray

      The value of the log of the normal CDF evaluated at x
