FISHERINV(y)The Fisher transformation is used to normalize the distribution of the correlation coefficient. This function reverses that transformation, allowing you to convert a transformed value back into a correlation coefficient.
=FISHERINV(0.5)結果: 0.462117
Calculates the inverse Fisher transformation for the value 0.5.
It is primarily used to perform hypothesis testing on correlation coefficients by transforming them into a normally distributed variable.
