Fractional Factorial Design

Factors: 6 Base Design: 6, 16 Resolution: IV
Runs: 16 Replicates: 1 Fraction: 1/4
Blocks: 1 Center pts (total): 0


Design Generators: E = ABC, F = BCD


Alias Structure

I + ABCE + ADEF + BCDF

A + BCE + DEF + ABCDF
B + ACE + CDF + ABDEF
C + ABE + BDF + ACDEF
D + AEF + BCF + ABCDE
E + ABC + ADF + BCDEF
F + ADE + BCD + ABCEF
AB + CE + ACDF + BDEF
AC + BE + ABDF + CDEF
AD + EF + ABCF + BCDE
AE + BC + DF + ABCDEF
AF + DE + ABCD + BCEF
BD + CF + ABEF + ACDE
BF + CD + ABDE + ACEF
ABD + ACF + BEF + CDE
ABF + ACD + BDE + CEF

在部分实施因子试验中,因子数为6个,分辨率 IV
生成元:E = ABC, F = BCD
请问3个字:ABCE ADEF BCDF 如何产生的,有无什么规律?
