同學(xué)你好,spenser說了LEI的優(yōu)點(diǎn):They are intuitive, simple to construct, require only a limited number of variables, and third-party versions are also available. 這些都是正確的,LEI的優(yōu)點(diǎn)有三個(gè)
1. Usually intuitive and simple in construction. 2. Focuses primarily on identifying turning points. 3. May be available from third parties. Easy to track.
所以Spenser說的優(yōu)點(diǎn)是完全正確的

Spenser說“the composite of leading economic indicators is based on an analysis of its forecasting usefulness in past cycles“,這不是與LEI對過去預(yù)測不準(zhǔn)的劣勢相違背嗎?

同學(xué)你好,Spenser這句話說的是LEI的分析方法,這句話本身是沒有問題的,這句話既不是優(yōu)點(diǎn)也不是缺點(diǎn),純粹只是說了分析方法。而你說的是LEI的劣勢,這個(gè)方法并不可靠,但這和spenser的話并不沖突,他說的是LEI的方法和有點(diǎn),你說了LEI的缺點(diǎn)。

LEI not worked historically,以及講義中的current data not reliable as input for historical analysis,這兩個(gè)缺點(diǎn)分別是什么意思?

同學(xué)你好
1. LEI方法過去的預(yù)測結(jié)果不準(zhǔn)
2. 把當(dāng)前的數(shù)據(jù)帶入歷史分析中是不靠譜的
