摘要

Purpose - The purpose of this paper is to consider the problem of using "black-box" methods to forecast catastrophe events, and illustrate the value of independent peer review. Design/methodology/approach - The problem with black-box catastrophe forecasts is the absence of both extensive validation data and impartial peer review. These issues may be addressed by comparing black-box forecasts with a set of naieve alternative forecasts provided by an independent party. To illustrate this approach, the historical hurricane forecasts of Dr William M. Gray, professor at Colorado State University, are considered and a simple ARIMA analysis is offered as a naieve alternative. Findings - The analysis shows that Dr Gray's complex forecasting methodology does in fact provide reasonable forecasts, and may indeed offer value beyond a naieve alternative model. Originality/value - The editorial identifies a major problem in catastrophe forecasting, and suggests one way to address this problem.

Gray博士的历史飓风预测,并提供了简单的Arima分析作为Naieve替代方案。 研究结果 - 分析表明,格雷博士的复杂预测方法实际上确实提供了合理的预测,并且确实可以提供超出Naieve替代模型的价值。 独创性/价值 - 社论确定了灾难预测中的主要问题,并提出了一种解决此问题的方法。
