Hi Peter! Me again! So I reached out to the competition organization and this is what they said:
His solution is totally right, that is a typo! I realized that the d = 0.0976 value would be considering only the first covariate w1, not the three of them.
Considering the three of them we have:
The solution arrays for this toy problem is the following:
- group1 = [1, 0, 0, 1, 0, 1]
- group2 = [0, 1, 1, 0, 1, 0]
The discrepancy value for this solution is d = 1.485
So I've gone ahead and updated the docs with this information. Sorry for the confusion! and I hope that helps answer your question.
