Bricks fly fine with sufficient thrust, but you have lff with a mu argument
that never gets used, so the negative log-likelihood is constant and mle()
cannot minimize it.
You need to read up on the definition of (log-) likelihood and write a proper
one for your problem.

I am analyzing animal movement pattern using levy flight pattern and want
to fit power function to observed data and estimate exponent using Maximum
Likelihood Estimation.
I am using
lff<-function(mu){1-1/mean(log(x))}
library(stats4)
mle(lff, start = list(mu = 1))
where x is the observed data.

Dear AllI'm trying to find the maximum likelihood estimator of a certain
distribution using nlm command but I receive an error as:
non-finite value supplied by 'nlm'
can't figure out what is wrong in my function
Any help?
Thank you in
