Abstract:
Yuan and Chan (Psychometrika, 76, 670–690, 2011 ) recently showed how to compute the covariance matrix of standardized regression coefficients from covariances. In this paper, we describe a method for computing this covariance matrix from correlations. Next, we describe an asymptotic distribution-free (ADF; Browne in British Journal of Mathematical and Statistical Psychology, 37, 62–83, 1984 ) method for computing the covariance matrix of standardized regression coefficients. We show that the ADF method works well with nonnormal data in moderate-to-large samples using both simulated and real-data examples. R code (R Development Core Team, 2012 ) is available from the authors or through the Psychometrika online repository for supplementary materials. Copyright The Psychometric Society 2015
