基于统计学习的分位数预测及其在GDP预测中的应用

Prediction of quantiles by statistical learning and application to GDP forecasting

Pierre Alquier, Xiaoyin Li

摘要:

在本文中,我们解决的问题,预测和置信区间的时间序列使用的统计学习方法和分位数损失函数。在第一次,我们表明,吉布斯估计(也被称为指数加权聚合)是能够预测,以及在一个给定的家庭中的最佳预测广泛的损失函数。特别是,使用Koenker和Bassett(1978)的分位数损失函数,可以建立置信区间。我们将这些结果应用于法国国内生产总值(GDP)增长的预测和置信区域的问题,有希望的结果。

英文摘要:

In this paper, we tackle the problem of prediction and confidence intervals for time series using a statistical learning approach and quantile loss functions. In a first time, we show that the Gibbs estimator (also known as Exponentially Weighted aggregate) is able to predict as well as the best predictor in a given family for a wide set of loss functions. In particular, using the quantile loss function of Koenker and Bassett (1978), this allows to build confidence intervals. We apply these results to the problem of prediction and confidence regions for the French Gross Domestic Product (GDP) growth, with promising results.
