I noticed that for the site\_id HANS, the observed number of nests both for adelie and chinstrap is 13381, with data collected on the same day 17/12/2003 on the ground. Maybe they do have exactly the same count, but could… --- ## [Missing observations in the 2014-2017 test data](https://community.drivendata.org/t/missing-observations-in-the-2014-2017-test-data/1233)

I was wondering if there were missing values in the 2014-2017 test data to which predictions are compared. If yes, then I guess these missing site-year pairs are not taken into account when evaluating predictions. If not… --- ## [Public and private leaderboard](https://community.drivendata.org/t/public-and-private-leaderboard/1210)

Just wanted to know what is the split of public and private leaderboard. --- ## [Prediction of nest counts, chicks, or adults?](https://community.drivendata.org/t/prediction-of-nest-counts-chicks-or-adults/1072)

It isn't exactly clear what the predictions should be. Observations can be of these 3 different types, but which one is used in the test set? --- ## [Submission Scoring](https://community.drivendata.org/t/submission-scoring/1170)

Hi, How does Driven Data choose the best submission for the private leader board ? The reason I ask this is because an individual's submission which ranks high on the public leader board may not be the highest in the… --- ## [Submission limits](https://community.drivendata.org/t/submission-limits/1122)

Hi Team, Unfortunately, I am not able to find the submission limit per day for this challenge. It seems to be one per day. Please, coud you confirm ? Thank you. --- ## [Nest\_counts time series has more than raw observation?](https://community.drivendata.org/t/nest-counts-time-series-has-more-than-raw-observation/1115)

Hi, Trying to understand how to arrive at the nest\_counts time series The description says we've extracted just the nest counts from the raw data and transformed them into a timeseries. To do that, we take the fol… --- ## [Site id in test set but not in train set](https://community.drivendata.org/t/site-id-in-test-set-but-not-in-train-set/1089)

There's a site id in the test set (STOK) that is not there in the train set. If this is deliberate where can I get the Lat/Long for this site id? --- ## [Site\_id and latitude/longitude precision](https://community.drivendata.org/t/site-id-and-latitude-longitude-precision/1082)

I noticed that some site\_id entries share the exact latitude and longitude information. One example is DAMO and DOBE. Since the latitude and longitude have up to four decimal points, the theoretical precision should be… --- ## [Penguin occurrence data](https://community.drivendata.org/t/penguin-occurrence-data/1074)

The rules state we are not allowed to use external penguin count data. However, are we allowed to use penguin occurrence data e.g. from GBIF. I assume we are, but just thought I'd check as it is a penguin "count" in th…
