Let’s visualize a GLM (logistic regression).
First laod some data:
data(tips, package = "reshape2")
Compute a glm:
glm_tips <- glm(sex ~ tip, data = tips, family = "binomial")
Plot the model using
## Warning: package 'dplyr' was built under R version 3.5.1
The curve does not look really s-typed (ogive) but that’s ok because the data suggest not a strong trend. The plot is not very beautiful either, but hey - it’s quick to produce 😁.
