CHIDIST

Description: Returns the one-tailed probability of the chi-squared distribution.

Syntax: CHIDIST(Number, Degr_Freedom)

• Number is the value at which you want to evaluate the distribution.
• Degr_Freedom is the number of degrees of freedom.

Remarks:

• Both arguments must be numerical.
• Number cannot be negative.
• Degr_Freedom must be an integer.
• Degr_Freedom must be >= 1 and <= 10^10.

• When used in an event analysis flowchart, the parameters must evaluate to numerical values. They can include:

• Numerical values

• Standard operands (+, -, *, /)

• Predefined mathematical functions (exp, log, sin, etc.)

• Event analysis internal functions

• Event analysis resources

• References to any ReliaSoft Workbooks

Example:

• CHIDIST(18.307, 10) = 0.050001
