FISHERINV(Number)

• is the value to find inverse of fisher transformation.
• FISHERINV(), returns the inverse of the Fisher transformation.

## Description

• This function gives the inverse of the Fisher transformation.
• We use this to test the correlations between set of data.
• The Inverse of the Fisher transformation is: i.e , then • It can be used to construct a confidence interval.
• A confidence interval (CI) is a type of interval estimate of a population parameter and is used to indicate the reliability of an estimate.
This function will give the result as error when the value is non-numeric.


## ZOS

• The syntax is to calculate FISHERINV in ZOS is .
• is the value to find inverse of fisher transformation.
• For e.g.,FISHERINV(0.4521..0.507..0.01)
Inverse Fisher transformation

## Examples

1. FISHERINV(0.6389731838) = 0.56419999998
2. FISHERINV(0) = 0
3. FISHERINV(0.1234) = 0.1227774315035342
4. FISHERINV(1) = 0.761594155955765
5. FISHERINV(-0.4296) = -0.4049869686465480
