Strange story
The following article introduces you to the FISHER function - one of the functions in the statistical function group is very popular in Excel.
Description: The function returns the Fissher transformation at x. This transformation creates a normal distribution function, using this function to test a hypothesis based on a correlation coefficient.
Syntax: FISHER (x)
Inside:
- x: Numerical value to convert Fissher .
Attention:
- If x is not a number -> the function returns the #VALUE! Error value .
- If x ≤ -1 or x ≥ 1 -> the function returns the #NUM! Error value
- Fissher transform equation is:
[z '= frac {1} {2} ln left ({frac {{1 + x}} {{1 - x}}} right)]
For example:
Calculate the value of x after performing the fissher transformation using the data in the following data table:
- In the cell to calculate enter the formula : = FISHER (C6)
- Press Enter -> the value of x after performing the fissher transformation is:
- Similarly copy to the remaining values are results:
- Where x ≤ -1 or x ≥ 1 -> the function returns the #NUM! Error value
Above are instructions and some specific examples when using FISHER function in Excel.
Good luck!
