Stats 101C Kaggle Competition Final Project
There are two competitions:
- A classification competition
- And a regression competition
Each competition accounts for 16% of your final course grade. Each competition is scored separately.
Grading of each competition:
- 4% Competition performance and R Script verification
- 12% Report
Competition performance grading:
First place and ties for first place: 4 points
Last place and ties for last place: 0 points
Everyone else in between first and last place earns points that are scaled.
For example, let’s say that at the end of the competition there are 12 unique positions on the leader

board. There might be more than 12 teams, but with ties, let’s say there are only 12 unique positions.
Having 12 unique positions means there will be 11 gaps. Each gap will be 4/11 = 0.3636 points. And the
scoring will be as follows:
- 1
st place (and any ties): 4 points
- 2
nd place (and any ties): 3.636 points
- 3
rd place (and any ties): 3.273 points
- Etc.
- 10th place (and any ties): 0.727 points
- 11th place (and any ties): 0.364 points
- 12th place (and any ties): 0 points
Each competition is scored separately. It is possible for a team/individual to get first place in one
competition and earn 4 points in that competition while ending up in last place for the other
competition and getting 0 points for that one.
R Script verification
You will submit an R script that shows how your predictions were made. I have provided a starting
template that imports the data and produces the necessary output file to submit to Kaggle.
Your R script will be run to verify that it does indeed produce the predictions you submitted to Kaggle.
If the predictions you submitted to Kaggle do not match the output produced by your R script, you will
get a 0 for the competition performance portion of your project grade. This rule is to prevent students
from making a model in R and then manually changing the predictions in the submission file to get a
higher score in the competition.
Similarly, your R script should not make predictions manually. It must use the trained model for making
predictions.
Report guidelines:
You will submit a PDF report explaining the model you fit. The report is worth 12 points.
The report will describe anything that is done to the data before the model is fit. This includes any data
cleaning, data manipulation, or data transformation that was performed. It includes any variable
selection or dimension reduction process or any new variables that were created. You don’t need to do
any of the above things in your script to get full credit, but if you do any of the above steps, they must
be explained in the report.
The report will describe what kind of model was chosen for the final prediction and submission.
The report will explain why you think your model is a good choice and/or any shortcomings of the model
and areas of improvement. This section should include how you evaluated your model performance.
(Your evaluation of model performance should not be, “I submitted the predictions to Kaggle and got a
score.”)
Report should be about 2 pages long.
