I have been given the following pdf :
fT (t; B, C) = ( exp(-t/C) - exp(-t/B) ) / ( C - B ) , (t>0) where the overall mean is B+C.
I am unsure as to how to write the log likelihood function of B and C.
The next part of the Q asks me to derive the equations that would have to be solved in order to find the max likelihood estimators of B and C.
I would be grateful for any help =)
