get.plausible: Read Conquest Plausible Values Output Files

In weirichs/eatModel: Educational Assessment Tools for IRT Modeling using Conquest or TAM

Read Conquest Plausible Values Output Files

Description

This function reads Conquest plausible value files and automatically identifies the number of cases, the number of plausible values and the number of dimensions.

Usage

get.plausible(file, quiet = FALSE, forConquestResults = FALSE)

Arguments

file	Character string with the name of the ConQuest plausible values file.
quiet	Logical: Suppress printing messages on console?
forConquestResults	This argument only applies if get.plausible is called by getResults to enhance performance.

Value

A data frame with one row per person containing the following columns:

case	Case number
ID	Identifier for this case
pv	Plausible values columns. Columns are named pv.[number of PV].[number of dimension]. For example, pv.5.2 refers to the 5th plausible value of the second dimension.
eap	Expected a posteriori (EAP) ability estimate for each person. Columns are named eap_Dim.[number of dimension]. For example, eap_Dim.2 refers to the eap estimate of the second dimension.
se.eap	Standard error of the EAP estimate. Columns are named se.eap_Dim.[number of dimension]. For example, se.eap_Dim.2 refers to the standard error of the EAP estimate of the second dimension.

Examples

file <- system.file("extdata", "twodim.pvl", package = "eatModel")
pv   <- get.plausible(file)
