Remarks
The Johnson SU distribution is a four parameter family of probability distributions.
The system is derived by transformations that make the data approximately normal. There are four variants of the distribution. These types are enumerated by the JohnsonDistributionType type.
Distribution | Definition |
---|---|
Normal | A normal distribution, based on the identity transformation. Also referred to as the SN form. |
Unbounded | A distribution unbounded on either side, based on a hyperbolic sine transformation. Also referred to as the SU form. |
Bounded | A distribution that is bounded on both sides, based on a logistic transformation. Also referred to as the SB form. |
LogNormal | A distribution similar to a log-normal distribution that is bounded on the left side, based on an exponential transformation. Also referred to as the SL form. |
