rcgam: Rating-curve generalized additive model

In markwh/rcmodel: Calibrate and Validate Rating Curves for Riverine Load Estimation

Description

Fits generalized additive models to log-log relationships using 'mgcv::gam', but incorporates aspects specific to hydrologic rating curves. Specifically, tracks the geometric mean of flow and concentration, adjusts for transformation bias, and calculates relevant fit statistics such as Nash-Sutcliffe efficiency (NSE)

Usage

rcgam(formula, data, timeout = 3, ...)

Arguments

formula	a GAM formula. See 'help("gam", package = "mgcv")' for details.
data	an object of class rcData, generated using 'makeModelData', or a data frame that makeModelData can use.
timeout	the amount of time in seconds to try mgcv::gam before stopping with a timeout error
...	further arguments passed to 'mgcv::gam'

Details

Dots get passed to mgcv::gam() call. All logarithms are base e (natural log) Arguments ending in "var" are names of objects that will be assigned in the function. logflowvar and logcvar will be shifted to have mean zero. POSSIBLY CHANGE THIS?
