# FISHERINV

## Content

This function returns the inverse of the Fisher transformation for a specified value.

## Syntax

`FISHERINV(value)`

## Arguments

The argument is the specified numeric value.

## Remarks

Use this transformation when analyzing correlations between ranges or arrays of data. This function calculates the inverse of the Fisher transformation, so if *y* = [FISHER](/spreadjs/docs/v16/formulareference/FormulaFunctions/statistical-functions/FISHER)( *x* ), then FISHERINV( *y* ) = *x* .

The inverse Fisher transformation is calculated as follows:

where y is the *value* argument.

## Data Types

Accepts numeric data. Returns numeric data.

## Examples

`FISHERINV(A43)`

`FISHERINV(R4C12)`

`FISHERINV(0.56)` gives the result 0.5079774329
