where:
\\(n\\) is the total number of observations in the (public/private) data set,
\\(xi\\) is your prediction of target, and \\(yi\\) is the actual target for \\(i\\).
\\(\log(x)\\) is the natural logarithm of \\(x\\)


## Submission Format

For every `id` in the dataset, the submission file should contain two columns: `id` which is the unique id for each data point from the testing dataset, and `result` which is the water quality measurement factor. The second column should be a space-delimited string value.

The file should contain a header and have the following format:
```
