Web15 apr. 2024 · An alternative is to use maximally selected rank statistics for the split point selection. As in conditional inference forests, splitting variables are compared on the p-value scale. However, instead of the conditional Monte-Carlo approach used in conditional inference forests, p-value approximations are employed. Websuch as maximally selected ˜2 and rank statistics, but also allows for direct construction of new test procedures for less standard test problems. As an application, a novel …
Web11 mei 2016 · With maximally selected rank statistics, the optimal split variable is determined using a statistical test for binary splits, which adjusts for the multiple testing of multiple possible split points. Thus, this approach naturally avoids split point selection bias.
