1.What is a logit and how do we compute class probabilities from the logit?

2.Compare and contrast linear and logistic regression methods.

3.Let x3 be the following vector:

x3 <- c(0, 1, 1, 2, 2, 2, 3, 3, 4)

Imagine what a histogram of x3 would look like. Assume that the histogram has a bin width of 1. How many bars will the histogram have? Where will they appear? How high will each be?
