In flexFitR: Flexible Non-Linear Least Square Model Fitting

Delta method generic function

Description

Delta method generic function

Usage

.delta_method_gen(fit, formula)

Arguments

fit	A fit object which is located inside a modeler object
formula	A formula specifying a function of the parameters to be estimated (e.g., ~ b * 500). Default is NULL.

Value

A data.frame of the evaluated formula.

Examples

library(flexFitR)
data(dt_potato)
mod_1 <- dt_potato |>
  modeler(
    x = DAP,
    y = Canopy,
    grp = Plot,
    fn = "fn_lin_plat",
    parameters = c(t1 = 45, t2 = 80, k = 0.9),
    subset = c(15, 2, 45)
  )
print(mod_1)
# Function of the parameters
predict(mod_1, formula = ~ t2 - t1, id = 2)
