A data frame with administrative information per item. Includes only items that are part of a Rasch model. See builtin_itemtable for an overview of all currently defined items.
builtin_itembankA data.frame with variables:
| Name | Label |
key | String indicating a specific Rasch model (the key) |
item | Item name, gsed lexicon |
tau | Difficulty estimate |
label | Label (English) |
instrument | Instrument code |
domain | Domain code |

key gsed2212.
