# NTJOHNSONSUDIST

Returns the Johnson SU distribution for the specified parameters.

## Syntax

NTJOHNSONSUDIST(

• x,
• Gamma,
• Delta,
• Lambda,
• Xi,
• Cumulative

)

#### Parameters

• x is the value for which you want the distribution.
• Gamma is a parameter of the distribution $\gamma$.
• Delta is a parameter of the distribution $\delta\;(>0)$.
• Lambda is a parameter of the distribution $\lambda\;(>0)$.
• Xi is a parameter of the distribution $\xi$.
• Cumulative is a logical value that determines the form of the function. If cumulative is TRUE, NTJOHNSONSUDIST returns the cumulative distribution function; if FALSE, it returns the probability mass function.
