How to reconcile the regression equation from spline terms (+ R code)

Splines are useful tools for capturing non-linearity in regression models, but oftentimes it is confusing what is going on behind the scenes. We go through an example modeling blood pressure with age showing how you can reconcile the regression equation when a spline term is added. This is useful not only for understanding the math, but also for enabling you to embed complex models into any application with a simple formula. 00:00 Introduction 02:34 Setting up in RStudio 03:05 Fitting a simple linear regression model 03:48 Adding a spline term 05:05 Initial recovery attempt 06:07 Identifying the knot locations 06:46 Expansion of power bases 08:48 Accounting for normalization 11:08 Finalizing the regression equation Blog post: https://www.centralstatz.com/posts/re...
