estimate_var_tsa: 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 only

• estimate_var_tsa_uvdrr Variance of $\rho$ corrected for univariate direct range restriction (i.e., Case II) and measurement error

• estimate_var_tsa_bvdrr Variance of $\rho$ corrected for bivariate direct range restriction and measurement error

• estimate_var_tsa_uvirr Variance of $\rho$ corrected for univariate indirect range restriction (i.e., Case IV) and measurement error

• estimate_var_tsa_bvirr Variance of $\rho$ corrected for bivariate indirect range restriction (i.e., Case V) and measurement error

• estimate_var_tsa_rb1 Variance of $\rho$ corrected using Raju and Burke's TSA1 correction for direct range restriction and measurement error

• estimate_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.

Usage

estimate_var_tsa_meas(mean_rtp, var = 0, mean_qx = 1, mean_qy = 1,
  ...)
estimate_var_tsa_uvdrr(mean_rtpa, var = 0, mean_ux = 1, mean_qxa = 1,
  mean_qyi = 1, ...)
estimate_var_tsa_bvdrr(mean_rtpa, var = 0, mean_ux = 1, mean_uy = 1,
  mean_qxa = 1, mean_qya = 1, ...)
estimate_var_tsa_uvirr(mean_rtpa, var = 0, mean_ut = 1, mean_qxa = 1,
  mean_qyi = 1, ...)
estimate_var_tsa_bvirr(mean_rtpa, var = 0, mean_ux = 1, mean_uy = 1,
  mean_qxa = 1, mean_qya = 1, sign_rxz = 1, sign_ryz = 1, ...)
estimate_var_tsa_rb1(mean_rtpa, var = 0, mean_ux = 1, mean_rxx = 1,
  mean_ryy = 1, ...)
estimate_var_tsa_rb2(mean_rtpa, var = 0, mean_ux = 1, mean_qx = 1,
  mean_qy = 1, ...)
