2 Factor Anova with Repetitions

I need to do a 2 Factor Anova Test, or any anova test at that. My problem is with how to notate my data for my tests.

I have 2 Factors, Eact with 4 levels, and 2 values at each level.

i.e. Factor B

1 2 3 4

1 a,b c,d e,f g,h

Factor A 2 i,j

..... and so on to complete.

How do I set up a matrix or get anova to read that each level for each factor has 2 values that need to be assessed?

i would use anovan(data,{factor1,factor2}), it's in my opinion a bit easier to handle. data is a column vector of length N, factor1 and factor2 can be column vectors or colum cells with length N.

you could also use it's 'nested' option

[Nicholas Danner]

So data would identify the values, factor1 would designate each value to either first or second spot in block factor2 would designate a set of values to each level

Is that correct?

[Jonas]

are a,b two values of a repeated measure, do they measure the same paramter? anovan can just handle one value per row, but if u measure two different things you could maybe do two anovas, one for each number of the pair. if you have repeated measures i think you have to have a look into ranova

[Nicholas Danner]

a and b are two separate values yes, for two tests done at the same factor A level and factor B level...
