Web11 mei 2016 · We therefore use maximally selected rank statistics for split point selection in random forests for survival analysis. As in conditional inference forests, p-values for association between split points and survival time are minimized. We describe several p-value approximations and the implementation of the proposed random forest … Web24 nov. 2008 · Summary Maximally selected statistics for the estimation of simple cutpoint models are embedded into a generalized conceptual framework based on conditional inference procedures. This powerful framework contains most of the published procedures in this area as special cases, such as maximally selected χ 2 and rank statistics, but …
Web4 apr. 2024 · According to the cut-off point of risk scores derived from maximally selected log-rank statistics, LIHC patients in the TCGA training cohort were divided into low and high-risk groups. The Kaplan–Meier method was utilized to estimate OS and the log-rank test was used to compare the differences of OS between the two groups. Web11 mei 2016 · However, linear rank statistics are utilized in current software for conditional inference forests to select the optimal splitting variable, which cannot detect non-linear effects in the independent variables. We therefore use maximally selected rank statistics for split point selection in random forests for survival analysis.
