archive 2025-07-28 Description, source and code snippet are the archive's method entry.
Given a training set drawn from an unknown d-variate probability distribution, QuantTree constructs a histogram by recursively splitting ℝᵈ. The splits are defined by a stochastic process so that each bin contains a certain proportion of the training set. These histograms can be used to define test statistics (e.g., the Pearson statistic) to tell whether a batch of data is drawn from ϕ₀ or not. The most crucial property of QuantTree is that the distribution of any statistic based on QuantTree histograms is independent of ϕ₀, thus enabling nonparametric statistical testing.

Usage over time archive 2025-07-28
Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
