| Summary : IRT Item-Person Map with \'ConQuest\' Integration
|
Description :
A powerful yet simple graphical tool available in the field of
psychometrics is the Wright Map (also known as item maps or item-person
maps), which presents the location of both respondents and items on the
same scale. Wright Maps are commonly used to present the results of
dichotomous or polytomous item response models. The \'WrightMap\' package
provides functions to create these plots from item parameters and
person estimates stored as R objects. Although the package can be used
in conjunction with any software used to estimate the IRT model (e.g.
\'TAM\', \'mirt\', \'eRm\' or \'IRToys\' in \'R\', or \'Stata\', \'Mplus\', etc.),
\'WrightMap\' features special integration with \'ConQuest\' to facilitate
reading and plotting its output directly.The \'wrightMap\' function
creates Wright Maps based on person estimates and item parameters
produced by an item response analysis. The \'CQmodel\' function reads
output files created using \'ConQuest\' software and creates a set of
data frames for easy data manipulation, bundled in a \'CQmodel\' object.
The \'wrightMap\' function can take a \'CQmodel\' object as input or it can
be used to create Wright Maps directly from data frames of person and
item parameters.
