Welcome to the video about the Full Factorial Design (Design of Experiment - DoE) in CAT. In this video a real case study about the crystal growth at NASA has been used as example of a Full Factorial Design: M.W. Burke, R. Leardi, R.A. Judge, M.L. Pusey, Crystal Growth & Design, 4, 333-337 (2001). We will see step by step all the outputs of the "Model computation" regarding the diagnostic, coefficients and the plots. Especially, we will see the very important function about the plot "semi-amplitude confidence interval". Finally, we will learn how to use the function "Prediction" in order to validate the model.
