Advanced response surface analysis. The main function RSA computes
and compares several nested polynomial regression models (full second- or
third-order polynomial, shifted and rotated squared difference model,
rising ridge surfaces, basic squared difference model, asymmetric or
level-dependent congruence effect models). The package provides plotting
functions for 3d wireframe surfaces, interactive 3d plots, and contour plots.
Calculates many surface parameters (a1 to a5, principal axes, stationary point,
eigenvalues) and provides standard, robust, or bootstrapped standard errors
and confidence intervals for them.
