Hi All,

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
