use fitdist() to fit normal distribution with GIVEN MEANS.

Good Morning,

I would like to fit my data with normal dstributions, which have FIXED means, so if I try to use fitdist() function I fail because adding the mean as input of course bias my output distribution parameters.

Is there a feasible solution to my problem?

Thanks in advance

@gabriele fadanelli,

If the mean μ is known in advance, then the maximum likelihood estimator for is

which is easy to calculate.
