[Gretl-users] testing for Long Memory using Fractional Integration test

Good morning, Please i want to investigate the integration properties of a variable so as to analyse the persistence in the series. 1. i want to test the fractional integration hypotheses within the interval (0,1) with grid ie, with step, 0.1. Is my procedure below correct? fractint ld_ELCNigeria(0) --all fractint ld_ELCNigeria(0.1) --all fractint ld_ELCNigeria(0.2) --all fractint ld_ELCNigeria(0.3) --all fractint ld_ELCNigeria(0.4) --all fractint ld_ELCNigeria(0.5) --all fractint ld_ELCNigeria(0.6) --all fractint ld_ELCNigeria(0.7) --all fractint ld_ELCNigeria(0.8) --all fractint ld_ELCNigeria(0.9) --all fractint ld_ELCNigeria(1) --all 2. how can i employ the Gil-Alana(2002) code in Gretl -- *Yusuf Abdulwahab Hassan.Department of Economics and Development Studies.Federal University of Kashere,Gombe.+234 8036830166.yabdulwahab(a)fukashere.edu.ng <yabdulwahab(a)fukashere.edu.ng&gt;*
