• Anscombe transform — In statistics, the Anscombe transform (1948) is a variance stabilizing transformation that transforms a random variable with a Poisson distribution into one with an approximately Gaussian distribution. The Anscombe transform is widely used in… …   Wikipedia

• Photon antibunching — generally refers to a light field with photons more equally spaced than a coherent laser field. More specifically, it can refer to sub Poisson photon statistics, that is a photon number distribution for which the variance is less than the mean. A …   Wikipedia
