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:
estimate_var_tsa_meas
: Variance of\rho
corrected for measurement error onlyestimate_var_tsa_uvdrr
: Variance of\rho
corrected for univariate direct range restriction (i.e., Case II) and measurement errorestimate_var_tsa_bvdrr
: Variance of\rho
corrected for bivariate direct range restriction and measurement errorestimate_var_tsa_uvirr
: Variance of\rho
corrected for univariate indirect range restriction (i.e., Case IV) and measurement errorestimate_var_tsa_bvirr
: Variance of\rho
corrected for bivariate indirect range restriction (i.e., Case V) and measurement errorestimate_var_tsa_rb1
: Variance of\rho
corrected using Raju and Burke's TSA1 correction for direct range restriction and measurement errorestimate_var_tsa_rb2
: Variance of\rho
corrected using Raju and Burke's TSA2 correction for direct range restriction and measurement error. Note that a typographical error in Raju and Burke's article has been corrected in this function so as to compute appropriate partial derivatives.
