FISHERINV(y)
- is the number.
is the number.Description
- This function gives the inverse of the Fisher transformation.
- We can use when the testing of correlations between set of data.
- The Inverse of the Fisher transformation is: ), then FISHERINV(y)=x.
- It can be used to construct a confidence interval.
), then FISHERINV(y)=x.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 y value is nonnumric.
Examples
- FISHERINV(0.6389731838)=0.56419999998
- FISHERINV(0)=0
- FISHERINV(0.1234)=0.1227774315035342
- FISHERINV(1)=0.761594155955765
- FISHERINV(-0.4296)=-0.4049869686465480
