NO.PZ2018091901000048 问题如下 Wakuluk’s approato economic forecasting utilizes a structurmol in conjunction with a ffusion inx to termine the current phase of a country’s business cycle. This approahprocesuccessful prections in the past, thus Wakuluk hhigh confinin the prections. Wakuluk’s approato economic forecasting: A.is flexible anlimitein complexity. B.cgive a false sense of precision anprovi falsesignals. imposes noconsistenof analysis across items or fferent points in time. B is correct. Wakuluk’s approato economic forecasting utilizes both a structurmol (e.g., econometric mol approach) ana ffusion inx (e.g., a leang incator-baseapproach). However, the two approaches have weaknesses: econometric mol approamgive a false sense of precision, ana leang incator-baseapproacprovi false signals. Two strengths of the checklist approaare its flexibility anlimitecomplexity, although one weakness is thit imposes no consistenof analysis across items or fferent points in time.解析Wakuluk的经济预测方法利用了结构模型(如计量模型方法)和扩散指数(如基于领先指标的方法)。然而，这两种方法都有弱点。比如计量经济模型方法可能会给人一种错误的精度感，而基于领先指标的方法可能会提供错误的信号。题目中没有体现的检查表方法的两个优点是它的灵活性和简单实用性(A不入选)，但是它也有缺点，它的一个缺点是在不同的项目或不同的时间点上没有强加一致性的分析（C不入选）。所以本题中只有B正确。 如题
