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
