This function returns the inverse of the Fisher transformation for a specified value.
FISHERINV(value)
The argument is the specified numeric value.
Use this transformation when analyzing correlations between ranges or arrays of data. This function calculates the inverse of the Fisher transformation, so if y = FISHER(x), then FISHERINV(y) = x.
The inverse Fisher transformation is calculated as follows:
where y is the value argument.
Accepts numeric data. Returns numeric data.
FISHERINV(A43)
FISHERINV(R4C12)
FISHERINV(0.56) gives the result 0.5079774329
