Common Probability Distributions

Subtract the mean of X from X and then divide it by the standard deviation of X.

Divide the mean of X by the standard deviation of X.

The mean of X is the standardized normal variable.

It is normal only if X and Y have the same mean.

It is always positive with positive skew.

If variable X is lognormal, then Ln(X) is normal

The sum of lognormal variables is lognormal.
