Symmetric Third Order Designs for sequential experimentation
Description
Generates symmetric sequential Third Order Design with 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
SeqTORD(v)
Arguments
