FISHERINV function - Function that returns the inverse of the Fissher transformation in Excel

The following article introduces you to the FISHERINV function - one of the functions in the statistical function group is very popular in Excel.

Description: The function returns the inverse value of the Fissher transformation . Use this function to analyze the correlation between two data arrays, if y = FISHER (x) -> FISHERINV (y) = x .

Syntax: FISHER (y)

Inside:

- y: The numerical value to perform the inverse of the Fissherinv transformation .

Attention:

- If y is not a number -> the function returns the #VALUE! Error value .

- Fissherinv transform equation is:

[x = frac {{{e ^ {2y}} - 1}} {{{e ^ {2y}} + 1}}]

For example:

Calculate the inverse value of y after performing the fissherinv transformation using the data in the following data table:

- In the cell to calculate enter the formula : = FISHERINV (C6)

- Press Enter -> the inverse value of y after performing the fissherinv transformation is:

- Similarly copy to the remaining values ​​are results:

- Where y is not a numeric form -> the function returns the #VALUE! Error value

Above are instructions and some specific examples when using FISHERINV function in Excel.

Good luck!
