Response Surface Analysis

Advanced response surface analysis. The main function RSA computes and compares several nested polynomial regression models (full polynomial, shifted and rotated squared differences, rising ridge surfaces, basic squared differences). The package provides plotting functions for 3d wireframe surfaces, interactive 3d plots, and contour plots. Calculates many surface parameters (a1 to a4, principal axes, stationary point, eigenvalues) and provides standard, robust, or bootstrapped standard errors and confidence intervals for them.
