FISHERINV(y)
- is the number.
is the number.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.
i.e 
, then 
This function will give the result as error when the value is non-numeric.
ZOS Section
- The syntax is to calculate FISHERINV in ZOS is .
- is the number.
- For e.g.,fisherinv(0.4521..0.507..0.01)
.
Examples
- FISHERINV(0.6389731838) = 0.56419999998
- FISHERINV(0) = 0
- FISHERINV(0.1234) = 0.1227774315035342
- FISHERINV(1) = 0.761594155955765
- FISHERINV(-0.4296) = -0.4049869686465480
