Calculate the variance of an estimator after Fisher's Z transformation
1 | FisherZ.Var(x, var.x)
|
x |
A numeric value, an estimator in the range of 0~1. |
var.x |
A numeric value, the variance of the estimator x. |
The variance of an estimator x after Fisher's Z transformation is \frac{var(x)}{(1-x^2)^2}{var(x)/(1-x^2)^2}.
Return a numerical value—the variance of an estimator after Fisher's Z transformation.
