...e(y == 0, 1, y/mu)) - log(ifelse(y == 1, 1,
(1 - y)/(1 - mu)))) - 2 + y/mu + (1 - y)/(1 - mu))
I've modified the `quasi' function accordingly (into `quasi2' given
below) and my results are very much in line with the ones cited by

+ family = quasi2(link = "logit", variance = "mu^2(1-mu)^2"),
+ data = leafblotch))
Call:
glm(formula = blotch ~ site + variety, family = quasi2(link = "logit",
