# Constructing the predictor insight graph table

In the previous exercise you learned how to calculate the incidence column of the predictor insight graph table. In this exercise, you will also add the size of the groups, and wrap everything in a function that returns the predictor insight graph table for a given variable.

Instructions

**100 XP**

- Group the basetable by
`variable`

. - Calculate the predictor insight graph table by calculating the target incidence and group sizes.
- Use the function
`create_pig_table`

to calculate the predictor insight graph table for the variable "gender".
