      In many natural processes, random variation conforms to a particular probability distribution known as the normal distribution, which is the most commonly observed probability distributions. The normal curve was first used in the 1700’s by French mathematicians and early 1800’s by German mathematician and physicist Karl Gauss.

      The model converges much faster than the other ones and do not oscillate. The reason for the fast convergence is the choice of parameters. With the LR-parameters the strike price is centred in the tree and the probabilities are given by De Moivre-Laplace theorem, which is an approximation of the normal distribution.
