Web11 mei 2016 · In this work, we propose to use maximally selected rank statistics [22, 23, 24] for CIF to avoid a change in the statistical approach for split variable and split point selection. 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 … WebThe maximally selected log-rank statistic for cutpoints between the 10% and 90% quantile of MGE using the upper bound of the P-value by Hothorn and Lausen (2003) can be computed by >library(maxstat) Package a A YexactRankTestsa A Z is no … meretricious consideration definition

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. WebA common statistical problem is the assessment of the predictive power of a quantitative variable for some dependent variable.
