The third line denotes how the model will be estimated. In the text above, the Nominal model is applied, thus "NO" is indicated and then the number of categories (options) for each of the ten items is provided, "NC=(5,5,5,5,5,5,5,5,5,5)". Because we are interested in estimating parameters for the Nominal model, we must also indicate which option is to be "keyed" as the highest (desirable or correct) option. Thus, "HI=(5,5,5,5,5,5,5,5,5,5)".
