I have a dataset that are normally distributed and I am trying to fit the data into a GLM model in R. The model that I used for a previous dataset had a binomial distribution and I used the GLM code: model1 <- glm(formula = Y$mat ~ X, family = binomial(link = "probit")). How would I specify the 'family' parameter for a 'normal' distribution as there doesn't seem to be a value for this in the documentation, and what is the default link function for a normal distribution?
