Tree estimation is in general based on recursively performing binary partitioning on the covariate space using some pre-defined splitting rule.  ...  In the setting with time-to-event data there are two splitting rules that are mostly adopted in growing survival trees: the log-rank splitting and log-rank score splitting.  ...

Transformation Forests [article]

Torsten Hothorn, Achim Zeileis
2018 arXiv   pre-print
The resulting models are fully parametric yet very general and allow broad inference procedures, such as the model-based bootstrap, to be applied in a straightforward way.  ...  A dedicated novel "transformation tree" algorithm able to detect distributional changes is developed.  ...  Your random forest version could perform better. 8 . 8 The way I understand your simulation setup is the following: You take real data sets, you fit each method, and then you use the parametric bootstrap  ...

Computing parametric yield adaptively using local linear models

Mien Li, Linda Milar
1996 Proceedings of the 33rd annual conference on Design automation conference - DAC '96  
The resulting models are then used as cheap surrogates for circuit simulation in Monte Carlo estimation of the parametric yield. Examples indicate the eciency and accuracy of this approach.  ...  Local linear models are used because they are less sensitive to dimension than polynomial models. Moreover, the resulting model can be made to be more accurate in some regions compared to others.  ...  The resampling and checking data set are generated locally several times during modeling. The number of data used is 195, which i s v ery close to 200 in [7] .  ...

Nowcasting in a Pandemic using Non-Parametric Mixed Frequency VARs [article]

Florian Huber, Gary Koop, Luca Onorante, Michael Pfarrhofer, Josef Schreiner
2020 arXiv   pre-print
This paper develops Bayesian econometric methods for posterior inference in non-parametric mixed frequency VARs using additive regression trees.  ...  We argue that regression tree models are ideally suited for macroeconomic nowcasting in the face of extreme observations, for instance those produced by the COVID-19 pandemic of 2020.  ...  For instance, to get to the leftmost terminal node involves checking one condition (one split), to get to the rightmost terminal node involves checking three conditions (three splits).  ...
