A Gamma distribution is sometimes used rather than a Normal (a) distribution when modelling a continuous response. What aspects of the data for the response might indicate that a Gamma distribution should be used? (b) The canonical link function for the Gamma distribution is the inverse function. An analyst for an insurance company wishes to develop generalised linear models assuming Gamma errors of claim size. Why might the analyst choose to use a log-link instead of the canonical one? 3.
