(FISHER(arg))
Returns the Fisher transformation at arg. This transformation produces a function that is normally distributed rather than skewed. Use this function to perform hypothesis testing on the correlation coefficient.
The arg value must be a number value between -1 and 1. The resulting variable value is the DOUBLE data type.
Example:
SET VAR vFisherResult DOUBLE = (FISHER(0.063))
SHOW VAR vFisherResult
0.063083548051763
