*2.3. At-Site and Regional PFE Estimation Methods*

Two estimation approaches for the frequency analysis of extreme precipitation, at-site (or pixel-based) and regional, are applied using the radar product and compared to each other. Uncertainties due to sampling effects are quantified in terms of confidence bounds using the difference between the 95th and 5th percentiles. The results of each method will also be compared to the corresponding gauge-based estimates that are reported in the NOAA Atlas 14 PFEs [18].
