In this assignment, you will need to build a Performance Factors Analysis model for this week's data set.

This data set is simulated data, which hopefully you would have recognized for yourself from the fact that students have names like "fail-o".

The variables in the data set are:

student: a deidentified ID for the imaginary student
item: the problem step in the learning system
skill1? skill2? skill3?: the knowledge components (skills) possibly involved in this item
firstattemptcorrectness: is the student action correct (1) or not correct (0)

You should complete this activity in Python. You do not receive any penalty for using hints.
