Abstract. We present an extension of Sasieni, Royston, and Cox’s bivariate
smoother running to the multivariable context. The software aims to provide
a picture of the relation between a response variable and each of several
continuous predictors simultaneously. This may be a valuable tool in
exploratory data analysis, before constructing a more formal multiple
regression model.
