FISHER (Number)

• is the value to find the Fisher transformation.
• FISHER(), returns the Fisher transformation.

## Description

• This function gives the value of Fisher Transformation for the given number.
• Fisher Transformation is used to test the hypothesis of two correlations.
• It is mainly associated with the Pearson Product-Moment Correlation coefficient for bi-variate normal observations.
• In , is the value which ranges between -1 to +1.
• The transformation is defined by :

where is the natural logarithm function and is the Inverse Hyperbolic function.

• This function will give the result as error when:
1. is non-numeric
2. or .


## ZOS

• The syntax is to calculate FISHER in ZOS is .
• is the value to find the Fisher transformation.
• For e.g.,FISHER(0.1..0.4..0.1)
Fisher Transformation

## Examples

1. FISHER(0.5642) = 0.6389731838284958
2. FISHER(0)= 0
3. FISHER(-0.3278) = -0.3403614004970268
4. FISHER(1) = Infinity
5. FISHER(-1) = -Infinity
