I'm trying to solve this
I have this pdf
I must find the maximum likelihood estimator of the expected value
I did this
The log of the last expression is
In its derivative the disappears
Without taking the log I end maximizing the same expression (the exponent of )
How can I proceed?
I see that I can express the pdf in this way:
This is the exponential distribution multiplied by a constant (but i know that it is defined for different values of x)
Is this a wrong path?
