... For example, if we know that major flooding occurs in a town on average every six years, gamma(4,6) models how many years it will take before the next four floods have occurred. Another example: An insurance company observes that large commercial fire claims occur randomly in time with a mean of 0.7 ...

... I.e Z counts the number of standard deviations that the observation lies away from the mean, where a negative value tells that we are below the mean. We note that • Z lies between -1 and 1 with probability 68% • Z lies between -2 and 2 with probability 95% • Z lies between -3 and 3 with probability ...
