If the following factorial survey was performed: 192 dimensions with 200 respondents answering 10 vignettes each. So, each vignette would have about 10 responses. The problem is that the dimensions were not randomized on the vignettes. If there were correlations between some of the dimensions, then one could use "blocking" and combine some of them? Would this then be a problem for an expert statistician? Is this also a situation that econometricians often encounter, dependence(?) or correlations between the independent variables?
