For the binary response variable y = 0 or 1, its mean is probability p = P(y = 1) . Most often used link function is logit link, i.e., r; = In (L). Other link functions that 1-? are used in practice: (a) probit link: 13 = (9-103). Where (I) represents the cumulative standard normal distribution, (b) log-log link: r1 = In [ln(1 - p)] . Plot the three link functions and comment on how they differ
