Item-based example item pool with standard errors (320 items).

Details

This pool is associated with the following objects:

  • itempool_bayes an item_pool object containing 320 items.

  • itemattrib_bayes a item_attrib object containing 5 item-level attributes.

  • constraints_bayes a constraints object containing 14 constraints.

Also, the following objects are intended for illustrating expected data structures.

  • itempool_bayes_data a data.frame containing item parameters.

  • itempool_se_bayes_data a data.frame containing item parameter standard errors.

  • itemattrib_bayes_data a data.frame containing item attributes.

  • constraints_bayes_data a data.frame containing constraint specifications.

Examples

itempool_bayes    <- loadItemPool(itempool_bayes_data, itempool_se_bayes_data)
itemattrib_bayes  <- loadItemAttrib(itemattrib_bayes_data, itempool_bayes)
constraints_bayes <- loadConstraints(constraints_bayes_data,
  itempool_bayes, itemattrib_bayes)
