WebThin plate splines are ideal for examining the combined effect of two continuous predictors on a single outcome, because of their multi-dimensional appearance. Rather than a single curve, thin plate splines are represented as a bendable surface. Each continuous variable is plotted on an individual x-axis, creating a bivariate, two-dimensional ...
