Table 5.

Estimates of the fixed effects (standard errors) from three biexponential quantile mixed-effects models with τ ∊ {0.1, 0.5, 0.9} and from the normal nonlinear mixed-effects model (NLME) using the Indomethacin Data. Standard errors for quantile regression estimates are based on 200 bootstrap replications. Bold denotes statistically significant at the 5% level.
