raw_to_rit: Raw to RIT conversions

In UO-BRT/exirt: Analyze data from the Oregon Extended Assessment

Raw to RIT conversions

Description

Creates a single dataframe that has the raw score, theta value and standard error associated with that raw score, the conversion to a RIT score and RIT standard error, and the performance level for the corresponding score. All conversions are returned for all tests.

Usage

raw_to_rit(round = TRUE, subscore = FALSE, db)

Arguments

round	Should the RIT scores be rounded? Defaults to TRUE. Note the rounding is done as typical, not as base::round() does. See the source code for the round2 function for more detail.
subscore	Do you want ELA subscores reported as well?
db	The db to get the pattern data from.

Value

data frame with raw score, theta value and standard error associated with that raw score, the conversion to a RIT score and RIT standard error, and the performance level for the corresponding score

Examples

library(exirt)
## Not run: 
ela_math_science <- raw_to_rit()
rdg_wri <- raw_to_rit(subscore = FALSE)

## End(Not run)
