Abstract:

The authors present a class of balanced-optimal fractional factorial designs of resolution V for the situation where there are 7 factors, each factor being at two levels, and the number N of runs being restricted to 56 or N or 68. The 29 x 29 covariance matrix of the estimates is also given for each design. Author
