Fig. 1From: Robust monitoring machine: a machine learning solution for out-of-sample R\(^2\)-hacking in return predictability monitoringTime-Varying Performances of the Proposed and the Monitoring Forecasts This figure plots the performances of the proposed and the monitoring forecasts relative to the benchmark. Positive values mean a forecast outperforms the benchmark. The horizontal axis is year while the vertical axis is the 60-month trailing moving average of difference in squared forecast error, multiplied by \(10^4\)Back to article page
