Cramp Function Distribution Definition
The (complex) cramp function distribution is a continuous distribution defined as :
The function integrates the normal distribution, giving the probability a normally distributed random variable Y (with mean 0 and variance ½), falls into the range [−x, x].
Cramp Function vs. Error Function
The term “(complex) cramp function” is seen in literature by Russian or Latvian authors (for example, see , , ), where it is usually denoted as W(x) . Elsewhere, it is known as the error function.
