getCorrectionFraction | R Documentation |
Computes the fraction of total concentration or flux prediction that is attributable to a correction such as the residuals correction of composite method models.
loadComp
models: The correction fraction for a composite method
(loadComp
) model is defined here as:
CF = (\sum |R| \Delta t) / (\sum L \Delta t)
where \sum
indicates a sum over all predictions, L
is the vector
of composite predictions of flux or concentration, R
is the vector of
interpolated residuals in the same format (flux or concentration, non-log
space) as L
, and \Delta t
is the vector of time periods
represented by the predictions.

newdata, ...)
## S3 method for class 'loadComp'
getCorrectionFraction(load.model,
flux.or.conc = c("flux", "conc"), newdata, na.rm = FALSE, ...)
load.model |
The load model from which to pull the correction fraction. |
flux.or.conc |
character. Should the metric be computed with respect to predictions of flux rate or concentration? |
newdata |
The data for which to compute the correction fraction, usually containing daily or instantaneous discharge. |

Other arguments passed to class-specific implementations of getCorrectionFraction. |
na.rm |
logical. Should predictions with NA values be excluded? |
A value between 0 and 1 indicating the fraction of total load that is attributed to a correction.
