qdm: Quantile delta mapping

In SantanderMetGroup/downscaleR: A climate4R package for statistical downscaling <http://meteo.unican.es/climate4r>

Quantile delta mapping

Description

Quantile delta mapping

Usage

qdm(o, p, s, precip, pr.threshold, n.quantiles, jitter.factor = 0.01)

Arguments

o	A vector (e.g. station data) containing the observed climate data for the training period
p	A vector containing the simulated climate by the model for the training period.
s	A vector containing the simulated climate for the variable used in p, but considering the test period.
precip	Logical indicating if o, p, s is precipitation data.
pr.threshold	Integer. The minimum value that is considered as a non-zero precipitation. precip = FALSE.
n.quantiles	Integer. Maximum number of quantiles to estimate. Default: same as data length.
jitter.factor	Integer. Jittering to accomodate ties. Default: 0.01.
