1.) You have two asset return vectors and a sample of T=1000 time series observations. You estimate power law functions for the absolute amount of returns and get the estimates = 3.28 and xMIN=2.96 for asset 1 and =3.15 and xMIN=4.01 for asset 2. Your calculations are that for 295 return observations of the first asset xxMIN is satisfied, whereas for 123 return observations of the second asset xxMIN is satisfied. Moreover, you find that for 87 return observations both asset returns are at the same time in the power law regime. Compute the co-fractality metric in its weak form. Is weak co-fractality statistically significant? What are the implications? ( 3 points)
