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
