Missing Dummy Variables?

hbsterling

With a dataset of distinct 154 countries, RM is not producing 154 zero/one dummy variables after the nominal to numerical operator. There are 9 variables that cannot be selected in select attributes/are just missing and I am not sure why it will not make a dummy code for every country?

Hi,

Select Attributes is not used to select the attributes for the next operator, it's removing all not selected from the example set.

You only need the "Nominal to Numerical" operator with attribute filter type single and attribute set to country.
You might also have to select "include special attributes" if your country attribute is used as i.e. a label.
