Unformatted text preview: fying the relevent components. (b) What is the canonical link? (c) Derive the mean and variance using the cumulant generating function. 4. Consider Y i Bin ( m i , i ) ,i = 1 ,...,n . Assume the logit link is specied. Derive the likeli-hood equations, the asymptotic covariance matrix for , and the deviance. 5. Show that if we specify the link function to be the canonical link, then the Newton-Raphson and Fisher Scoring algorithms are identical ( Hint : just need to show that expected and observed information matrices are the same for this case.)...
