Generalized Linear Models (GLM) in R: Part 2 EPID 799C Fall 2018 Let’s start HW4! (Get your births dataset ready)

Overview A working class! Expect to be very similar to homework 4, coming out soon

Crude effects Create a summary data.frame/table for crude effects: Using either dplyr:: functions or table() and prop.table() as we did in class, report the effect of early prenatal care on preterm birth by: the crude risk difference  just do this for now …the crude risk ratio ? …the crude odds ratio ?

Crude effects by race-ethnicity Create a summary data.frame/table for crude effects: Using either dplyr:: functions or table() and prop.table() as we did in class, report the effect of early prenatal care on preterm birth by: the crude risk difference  just do this for now …the crude risk ratio ? …the crude odds ratio ?

Let’s make this!

Let’s make this….but how? df structure? ggplot aes mappings? geometries? tweaks? Scales Title/subtitle/caption Note Theme …more?

Let’s make this!

BUT HOW?! Models Combine First: ggplot df looks like…? Base Dplyr Dplyr + purr Even more advanced purrr! First: ggplot df looks like…?
