文摘
- •
Least squares method is not appropriate for estimating
of Barabási–Albert graphs.- •
A modified version of Clauset et al. (2009) is more preferable for estimation.
- •
Simulated graphs show that exponent is not the theoretical
for small graphs.- •
Value of
is also dependent on number of edges added, m, for small graphs.- •
Smaller value of m results in larger value of
for all graph sizes.
