A new method of Hansen solubility parameters (HSPs) prediction was developed by combining the multivariate adaptive regression splines (MARSplines) methodology with a simple multivariable regression involving 1D and 2D PaDEL molecular descriptors. In order to adopt the MARSplines approach to QSPR/QSAR problems, several optimization procedures were proposed and tested.

This motivates the most common choice (8) w(x, x') = K(Ix - x'I/s(x)), with Ix - xil being a (possibly) weighted distance between x and x', s(x) is a Analyses were performed using multivariate adaptive regression splines (MARS), a technique that uses piece-wise linear segments to describe non-linear relationships between species and environmental variables. Multivariate Adaptive Regression Splines (MARS) is a non-parametric modelling method that extends the linear model, incorporating nonlinearities and interactions between variables.

Friedman, Stanford Linear Accelerator Center and Department of Statistics Stanford University Stanford, California 94309 ABSTRACT A new method is presented for flexible regression modeling of high dimensional data. The Multivariate adaptive regression splines algorithm is best summarized as an improved version of linear regression that can model non-linear relationships between the variables. While I demonstrated examples using 1 and 2 independent variables, remember that you can add as many variables as you like. MULTIVARIATE ADAPTIVE REGRESSION SPLINES 5 totically any weight function that places dominant mass in a (shrinking) convex region centered at x will work. Multivariate adaptive regression splines (MARS) provide a convenient approach to capture the nonlinear relationships in the data by assessing cutpoints (knots) similar to step functions.
