Plotting‐position estimators of L moments and L moment ratios have several disadvantages compared with the “unbiased” estimators. For general use, the “unbiased” estimators should be preferred. Plotting‐position estimators may still be useful for estimating extreme upper tail quantiles in regional frequency analysis.
