I was doing some research as to what type of probability distribution was the best use when trying to predict a stocks price for over a certain time period.
My research has led me to believe that a lognormal distribution is the most widely used distribution model for such purposes.
I have attached the equation for the lognormal distribution formula.
What I want to know is that how do I calculate the mean and the standard deviation of a lognormal distribution.
When I was researching this I received conflicting information I would really appreciate it if someone can point out me to the right direction.
Thanks in advance
