Paper said 0.275. We got 0.2748.

The code and data produced the same result. That doesn't prove the study's method is right.

Check this yourself

You don't have to trust us or the . With Docker and Node installed, this retraces the claim on your own computer and compares the number:

git clone <this repository> && cd rerun && pnpm install && pnpm sandbox:build
pnpm verify-claim 31

How much evidence is behind this?

Each step is a tougher test. Only the first one decides who wins the market.

  1. 1. ✓

    The Lab's retrace of the code and data named in the claim

    The Lab retraced the code and data and got a number inside the claim's range. YES wins.

Coming next: a data-leakage check, for the same rows in training and test data, and a maths check on the statistics a paper reports. Neither has run on this claim.

Even all three steps can't prove the science is true. They show how well this result stands up to checking.
