Model3SdErrClimTaper: Three-sigma error specification assuming errors are smaller...

In NCAR/rwrfhydro: R tools for the WRF Hydro Model

Description

Model3SdErrClimTaper models three-sigma errors (same units as input) as smallest (qntlIncpt intercept is some climatological quantile) at "climatological" observations (qntlClim, e.g. median = .5) and grow to some maximum percent error (pctErr). This is expressed by
quantile(data, qntlIncpt) + pmin( pctErr*data, pctErr*abs(data-quantile(data, qntlClim)) )

Usage

Model3SdErrClimTaper(data, qntlIncpt = 0.05, qntlClim = 0.5,
  pctErr = 0.15)

Arguments

data	Numeric The values for which errors are to be modeled.
qntlIncpt	Numeric The quantile of historical observations to be used as minimum error or intercept.
qntlClim	Numeric The quantile of historical observations to be used as observation value of minimum error.
pctErr	Numeric The percent error associated with the observations.
