It demonstrates the Granger test of causality as a model to test the correlation-ship between time series. Then it introduced in detail the principles and approaches of both liner and non-liner Granger test of causality.(1) In the following part, this article analyzed the warrant dose-price relations and the relationship of the prices movements between warrant and its target stock, using the approaches of liner and non-liner Granger test of causality respectively. It aims to study the actual operational state in our native market and promote significant suggestion in the development of financial derivatives markets.(2) In the analysis, this article uses nonparametric paired comparison test model to figure out whether it's obvious in the Granger causality between the markets of warrant and its target stock.
