# Does a <MISSING> score field indicate that the column was excluded from training?

> Suggest Edits

A `<MISSING>` score field typically means that the column was not used during training. This could be due to several reasons—for example, Kumo may have assigned the column with a `Null` encoder internally, despite being designated as a multicategorical stype. Also, Kumo supports a maximum of `500` distinct values, so surpassing this threshold would default to a null encoder.
