This toolbox contains some utility functions for classical design of experiments and response surface analysis.
The two main functions are:
reg - linear regression
rsreg - quadratic response surface regression
Both the functions have same options but different defaults. The regression functions return "rsreg" object, with the following methods defined:
parameters
residuals
predicted
r2
cook
resplot
normalplot
quadplot
cana
gradpath
There are some examples in the examples directory.
The code has been used for teaching statistical design of experiments and it is provided as is with no warranties or promises about its usability. The code uses some files from DATANA toolbox by kind permission of ProfMath Ltd. Comments and suggestions for improvement are welcome.
