These data are from a central composite design with 2 factors in 2 blocks. The design variables are in actual, not coded, form.
ChemReact ChemReact1 ChemReact2
A data frame with 14 observations on the following 4 variables.
a numeric vector; design variable with settings of 80, 85, and 90.
a numeric vector; design variable with settings of 170, 175, and 180.
a factor with levels
B1 is a first-order design with 3 center points.
B2 consists of axis points and 3 more center points.
a numeric vector; response variable: yield of the chemical process.
ChemReact2 are the separate blocks.
Each has 7 runs and three variables (
