dot-delta_method: Delta method point estimation

In flexFitR: Flexible Non-Linear Least Square Model Fitting

Delta method point estimation

Description

Delta method point estimation

Usage

.delta_method(fit, x_new, se_interval = "confidence")

Arguments

fit	A fit object which is located inside a modeler object
x_new	A vector of x values to evaluate the function.
se_interval	A character string. "confidence" or "prediction".

Value

A data.frame of the evaluated values.

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)
# Point Prediction
predict(mod_1, x = 45, type = "point", id = 2)
