Calculate the Central Difference Approximation of the First Derivative

Description

This function calculates the central difference approximation of the first derivative of a generalized additive model (GAM) with respect to a specified predictor variable.

Usage

central_diff(gam_object, newdata, x, h)

Arguments

gam_object	A fitted GAM model.
newdata	A data frame containing the values of predictor variables used to calculate the derivative.
x	Name of the predictor variable with respect to which you want to calculate the derivative.
h	Step size for the central difference approximation (default = 0.005)

Value

A numeric vector representing the central difference approximation of the first derivative.
