STATISTICS, NEUROSCIENCE Correction for “A study of problems encountered in Granger causality analysis from a neuroscience perspective,” by Patrick A. Stokes and Patrick L. Purdon, which was first published August 4, 2017; 10.1073/pnas.1704663114 (Proc Natl Acad Sci USA 114: E7063–E7072). The authors wish to note the following: “In the Discussion section of our paper, we misunderstood the method described in Barnett and Seth (25) to compute the conditional Granger causality. We realize now that the spectral factorization method they describe can be used to obtain the conditional Granger causality with a single model fit, which would avoid the computational problems associated with separate model fits. We apologize for this error.” 25. Barnett L, Seth AK (2014) The MVGC multivariate Granger causality toolbox: A new approach to Granger-causal inference. J Neurosci Methods 223:50–68.
