Spotting the danger zone - Forecasting financial crises with classification tree ensembles and many predictors
نویسنده
چکیده
To improve the detection of the economic ”danger zones” from which severe banking crises emanate, this paper introduces classification tree ensembles to the banking crisis forecasting literature. I show that their out-of-sample performance in forecasting binary banking crisis indicators surpasses current best-practice early warning systems based on logit models by a substantial margin. I obtain this result on the basis of one long-run(1870-2011), as well as two broad post-1970 macroeconomic panel datasets. I particularly show that two marked improvements in forecasting performance result from the combination of many classification trees into an ensemble, and the use of many predictors.

متن کاملClassification by ensembles from random partitions of high-dimensional data
A robust classification procedure is developed based on ensembles of classifiers, with each classifier constructed from a different set of predictors determined by a random partition of the entire set of predictors. The proposed methods combine the results of multiple classifiers to achieve a substantially improved prediction compared to the optimal single classifier. This approach is designed ...

متن کاملHeterogeneous Ensemble Classification
The problem of multi-class classification is explored using heterogeneous ensemble classifiers. Heterogeneous ensembles classifiers are defined as ensembles, or sets, of classifier models created using more than one type of classification algorithm. For example, the outputs of decision tree classifiers could be combined with the outputs of support vector machines (SVM) to create a heterogeneous...
