Q about ranking

2nd (Invited Participants) Challenge

How should the actual values be ranked? Given that some values have more than 10 decimal places, is it advisable to truncate these values to just 3 decimal places before ranking, or should the ranking process incorporate the entire precision of up to 10 decimal places?

Regarding predictions, in cases where identical ranking results are obtained for the some subjects, should these subjects be assigned the same rank, and should they be additionally labeled to reflect this equality? Or just label them in order and denote they’re tie.

Hi @Joe,

Thank you for the thoughtful question. We are truncating values to 2 decimal places for rank calculations.

It can be tricky to rank subjects when the values differ at much lower decimal places. In this case, I would consider assigning them the same rank, as you suggested. Rank ties are allowed, and we will identify them in the submission file when two or more subjects have the same rank. You don’t have to label them separately.

I hope this helps.
