FISHERINV(y)

• $y$ 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: $x=(e^{2}y-1)/(e^{2}y+1)i.e.,y=FISHER(x$), then $FISHERINV(y)=x$.
• 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 y value is nonnumric.
