Comparing probits and logits
You learned about probit and logit link function in the previous chapter.
Now, you will learn how to plot them together with ggplot2.
The purpose of this exercise is to show you that the two are often very similar and also to show you how to change link functions with ggplot2.
Your plot, gg_jitter, has been loaded for you and you will use this with geom_smooth().
Also, you will change the colors of your curves and remove the shaded areas to make the plot easier to read.

Instrucciones del ejercicio
- Plot a probit curve by setting the first family to use a
probitlink usingbinomial(link = 'probit'), the color to'red', andsetoFALSE. - Plot a logit curve by setting the first family to use a
logitlink usingbinomial(link = 'logit'), the color to'blue', andsetoFALSE.
