BaRatin stage-discharge rating curve model

Source: R/model.R
model_rating_curve.Rd

A hydraulically-controlled stage-discharge relationship of one to three segments, with a log10-space normal residual likelihood.

Usage

model_rating_curve(
  stage,
  discharge,
  segments = 1L,
  parameters = NULL,
  parameter_values = NULL,
  use_default_flat_priors = NULL
)

Arguments

stage

numeric vector of stage observations.

discharge

numeric vector of discharge observations, aligned with stage.

segments

number of hydraulic control segments (1 to 3).

parameters

optional model_parameter() object or list of them, setting bounds, fixed flags, priors, or starting values.

parameter_values

optional numeric vector of all parameter values, applied last.

use_default_flat_priors

logical; set FALSE alongside a custom prior.

Value

An object of class corehydro_model.
