  "Description": "Advanced response surface analysis. The main function RSA\ncomputes and compares several nested polynomial regression\nmodels (full second- or third-order polynomial, shifted and\nrotated squared difference model, rising ridge surfaces, basic\nsquared difference model, asymmetric or level-dependent\ncongruence effect models). The package provides plotting\nfunctions for 3d wireframe surfaces, interactive 3d plots, and\ncontour plots. Calculates many surface parameters (a1 to a5,\nprincipal axes, stationary point, eigenvalues) and provides\nstandard, robust, or bootstrapped standard errors and\nconfidence intervals for them.",
