问题如下：

Cambo compares her business cycle forecasting approach to the approach used by the chief economist. Cambo bases her equity market forecast on a time-series model using a composite index of leading indicators as the key input, whereas the chief economist uses a detailed econometric model to generate his economic forecasts.

Discuss strengths and weaknesses of the economic forecasting approaches used by Cambo and the chief economist.

解释：

这句话中  time-series model 就是数量经济模型吧， 为何答案按照LEI的model处理？

嗨，努力学习的PZer你好：


因为题目说的是on a time-series model using a composite index of leading indicators as the key input

在数量模型基础上，运用了LEI。

所以和另一个人预测相比，这里运用了LEI，那就是比较LEI和另一个人数量模型的优缺点。

如果这里也看成数量模型，那题目本身就没有意义了。

NO.PZ202105270100000203 题目中的inx方法也用到了时间序列模型，但是还被认为是inx方法，是因为inx是key input吗？如果inx只是其中一个input就是综合了mol和inx的方法吗？
