Asymmetric Third Order Designs for sequential experimentation
Description
Generates asymmetric sequential third order design for v (3 <= v <= 9) factors in two blocks. Block I gives a second order design for the first stage of the experimentation. If lack of fit of the second order model is found to be significant, then further experimentation can be done with the design given in block II. Runs from block-I and block-II combined form a third order design. It also gives G-efficiency of the third order design.
Usage
Asymseq(v)
Arguments
v |
Total number of input factors |
Value
Third order design in two blocks
Note
The user is given with a set of mixed level response surface designs and after entering the serial number of any of the designs from the displayed set, the chosen design will be generated and displayed.
