A Demo Dataset (Spline)

This is a simple dataset with nonlinear relationships between the outcome and mediators. It is used simply to illustrate the design of multimedia. The mediator->outcome effect is generated from a random spline function.

Usage

demo_spline(n_samples = 5000, tau = c(2, 2))

Arguments

n_samples

The number of samples to generate in the toy example

tau

The true direct effects associated with the two outcomes. Defaults to 2, 2.

Value

xy A data.frame whose columns include the treatment, mediation, and outcome variables.
