Howdy, Sorry if this is an iteration of an earlier post. I have a sets of data that are roughly 8x4000 in matrix form. In other words we have many sets of data that each contain 8 populations of 4000 samples each. Our goal is to first prove that each experiment of 8 populations are similar. Following that we want to extend this idea and show that the experiments are similar. I know this has been done and is availiable in packages such as StatView but they have the unfortunate disadvantage of requiring the user to manually input (cut/copy/open) each datafile. This is not practicle for us because we have hundreds of these to do. I want to run an ANOVA on these and I'd like to find a pre-written package that has an ANOVA function that can deal with a large matrix and then output a report similar to Regress[]. Ideally the package might have options for post hoc tests (ie Fisher, Dunn), although this is not absolutely necessary for our current data sets. Can anyone give me a little direction where I can find such a package? We'd be willing to purchase it if it is commercially availiable. I've looked through MathSource, the Mathematical Journal and whatever books on Mathematica I've been able to easily obtain and I haven't seen something like this. ..Thank's in advance, david -- David A.
