Should a finite sample adjustment be made? (1994), Automatic Lag Selection in Covariance Matrix Estimation. Review of Economic Studies, 61, 631--653.
Details. For type = "correlation" and "covariance", the estimates are based on the sample covariance. (The lag 0 autocorrelation is fixed at 1 by convention.)
