An error was subsequently identified in Figure 3. The reference lines in Figure 3 for Vd, OMCL and OMVd were incorrect and the reference line was missing for Sigma parameter in Figure 3. The reference lines represent the true values for each parameter. These values should be 1, 0.15, 0.15 and 0.086 for Vd, OMCL, OMVd and Sigma, respectively. The incorrect reference lines do not affect any discussion and conclusion of this paper. The corrected figure is shown below.
