# 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
