FISHERINV

Description: Returns the inverse of the Fisher transformation. If y = FISHER(x), then FISHERINV(y) = x.

Syntax: FISHERINV(y)

• y is the value for which you want to perform the inverse of the transformation.

Remarks:

• y must be a number.
• The equation for the inverse of the Fisher transformation is:

• When used in an event analysis flowchart, y must evaluate to a numerical value. It 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:

• FISHERINV(0.972955) = 0.75
