For the Poisson distribution the interest is in a random variable, X, that represents the number of occurrences of an event within a fixed time.
The truncated Poisson distribution on the given range [0, [n.sub.i]] is obtained by normalising the Poisson distribution, as follows:
gamma or Poisson distribution, with a choice of three link functions:
Whenever the assumption of Poisson distribution does not hold, statisticians tend to adopt alternative models to strengthen the quality control process.

The model structure can be based on a normal, gamma or Poisson distribution, with a choice of three link functions: the identity, logarithm and reciprocal link functions.
