QMEDfseSS: QMED factorial standard error for gauged sites
Description
Estimates the median annual maximum flow (QMED) factorial standard error (FSE) by bootstrapping the sample
Usage
QMEDfseSS(x)
Value
The factorial standard error for the median of a sample.
Arguments
x
a numeric vector. The sample of interest
Author
Anthony Hammond
Details
The bootstrapping procedure resamples from the sample N*500 times with replacement. After splitting into 500 samples of size N, the median is calculated for each. Then the exponent of the standard deviation of the log transformed residuals is taken as the FSE. i.e. exp(sd(log(x)-mean(log(x)))), where x is the bootstrapped medians.
