estimate_abilities

R Documentation

High-level function to estimate/create student estimates

Description

This function does the modeling and pulls the student estimates for every grade/content area (unless a specific grade/content area is supplied). Student estimates are computed with all field-test items removed.

Usage

estimate_abilities(test, single_df = TRUE)

Arguments

`test`	Either a list of test score data from which to estimate models or a single data frame with the item-level data. Note, this can be all tests. It does not have to be a list of only one content area, for example.
`single_df`	Should a single data frame be returned? Defaults to `FALSE`, in which case a list of data frames is returned (assuming) `model_ob` is a list of models. Otherwise a single data frame is returned, which may be generally useful, but is less useful when passing the results to other functions in the package.
