Right now the models work on arrays but they should be able to work with other input like dataframes, tables, etc. This will also require figuring out what people usually use to read and manipulate their data in Julia. Getting this done will probably be a v0.4 task.
Base on c7e2e82 we should now be able to initialize estimators with dataframes or similar types that can be converted to matrices and vectors by Matrix{Float64}(x) and x[:, 1], so I am going to close this issue.
