Box-Cox transformation of monthly Malaysian gold price range
Gold has a long history in trading over the past decades until its role in trading was replaced by the introduction of banknotes and coins. Gold is undeniably one of the prime commodities in investments and as well as a hedging tool. Thus, it is important to study the fluctuation in monthly gold pri...
