ccd_analysis: Response surface regression analysis of CCD data

In rsurface: Design of Rotatable Central Composite Experiments and Response Surface Analysis

Description

For the simultaneous production of response surface analysis output by rsm used in combination with graphics in the second-order polynomial approach. The predictor variables must be named “Factor1”, “Factor2”, etc., while the response variable must be named “Response”. The output includes regression model fitting and plot of the fitted response surface.

Usage

ccd_analysis(x)

Arguments

x	the matrix of experimental data that contains columns with the uncoded levels for each experimental factor and the observed values for the response variable in the rightmost column.

Value

The user will be prompted to enter “1” for a 3-D plot of the response surface, or “2” to plot the contour of the predicted variance of the response

“Data.For.Analysis”, includes the data set and the coding coefficients for the transformation of the independent factors

“Response.Surface.Summary”, includes the response surface for variable, hypothesis tests for linear, quadratic, and crossproduct terms, lack of fit test, parameter estimates, the factor ANOVA table, canonical analysis, and eigenvectors
