Factorial designs with all the factors with two levels are called 2k factorial designs and open a large number of possibilities for experimental designs. A full factorial ANOVA allows us to realize which effects are significant. In a 2k factorial design it may be necessary to control the ...

析因设计(factorial experiment):设有k个因素,每个因素有lj个水平(j=1,2,...,k),析因设计的处理组是k个因素在lj个水平的交叉分组,称为l1,l2,...,lk析因设计。如果k个因素的水平都为L,称为Lk析因设计。最常见、最简单的是2×2=2²析因设计[5]。 正交设计(the orthogonal design):正交设计是不全面试...

I have learned about repeated measures ANOVA but is it possible to have a repeated measures factorial design? So if you have factor A with 2 levels and factor B with 2 levels where each combination has 2 units and each unit is measured three times. Is there another name for this design?
