Simulation results (based on calcium) for estimating standard errors: ratio of standard errors of quantiles to simulated standard errors for two methods (n = 300 simulations). NCI= standard errors from the NCI method; ISU= standard errors (Taylor linearization) from the ISU method. Lines represent the 25th and 75th percentiles of the ratios.
