The Causal Relationship Between Stock Markets: Awavelet Transform-Based Approach

Dalam tahun kebelakangan ini, harga pasaran saham adalah salah satu daripada petunjuk ekonomi yang paling penting yang mendedahkan status ekonomi sesuatu negara serta menerokai hubungan kalangan negara-negara di dunia. Seperti yang sedia maklum, harga pasaran saham adalah tidak menentu dan mengan...
