Hi everyone!

Any ideas of how to solve this problem?

Error in B %*% Z : non-conformable arguments

So the columns doesnt match? But what is B and what is z? Where can I find info about which one is B and which one is z? My matrices are not named B and z.

Thanks!

Edit: Ok, z was the dumvar matrix. I thought it should be, but I still dont know where to find information about the letters used for matrices.
