In this study, we developed an inference procedure for the neural network using the bootstrap approach, and applied it … to the market efficiency of the Nigerian exchange rate. Data used are exchange rate values from 2001 to 2015. We … conducted a test on the market efficiency hypothesis, including test for relevance of individual and joint network inputs using …
