Dear all,

I'm using igraph for some analysis about the network I have. I have a
question about the function "power.law.fit".

I wonder if there is any test for checking whether the  "power.law.fit" is
good for the input, i.e., under which situation, could we use this function
to get a reliable result. I'm afraid even I input a random graph without any
property of "power-law" characteristics, it will returns an outcome which
seems to be a fit to available data while it has no meaning to us. Is there
any index like "goodness of fit" ?

Thank you for any comments.

Best!
