Taylor Series Approximation of effect-size variances corrected for psychometric artifacts

Description

Functions to estimate the variances corrected for psychometric artifacts. These functions use Taylor series approximations (i.e., the delta method) to estimate the corrected variance of an effect-size distribution.

The available Taylor-series functions include:

Notes

A typographical error in Raju and Burke's article has been corrected in estimate_var_tsa_rb2() so as to compute appropriate partial derivatives.
