Hello
I'm a newbie here. I need help on how to find mean and standard deviation for a lognormal distribution. I've been searching on the internet but cant find the answer.
Here is my question.
Let say
X = b x c x sqrt(d)
and b is assumed to follow lognormal distribution with mean 1.26 and standard deviation 0.33.
c is a constant which is equal to 1.392
and d is also follow lognormal distribution with mean 0.833 and standard deviation 0.15
so X should also be lognormal distributed right?
My question is what is the mean value and standard deviation of parameter X?
Appreciate if someone can help me here
Thanks
