Interactions specification

[ankaselivanka123]

Hello all,

I am trying to generate an efficient design to estimate all possible interactions using the normally distributed priors for the main effects; overall there are 100 parameters for the model with all 2-way interactions. I have 5 attributes with 3 levels each, dummy coded. When I input my script(see below), Ngene shows an error: Two identically named attributes do not have consistently specified levels: 'alt1.mobility', 'alt1.mobility'.
Could you please advise me upon this issue?

Thanks in advance!

Hi

This post is about Ngene syntax, not design theory or designs in general. Can you please re-post it the other section of the forum specific to Ngene and Ngene syntax and we will answer the question.

Thanks

John
