Answer: A: question regarding unbalanced two way anova with interaction term
... James, The underlying issues is that the interaction model requires all 4 cells to compute the interaction term. Essentially the interaction term is defined as a contrast between the four cell means. Since one does not exist, the interaction term is not estimable. Max -----Original Message----- ...

Answer: A: rma on new samples
... There are a few ways to do this. The basic issue is that the RMA normalization and summarization steps use data across multiple chips. There is a package called refRMA that normalizes to a pre-defined database of data generated by GeneLogic. See http://www.biomedcentral.com/content/pdf/1471-210 ...

rma on new samples

I have a training data set which I use to process the data (rma, center, scale etc.) for use with various models. Once I get the models trained, I'll be applying them to future data as they come in. D ...
