to meet CRAN requirements.runRSSS()

method is used.runLinking()

) in example datasets for clarity. The package functions do not use these columns.loadData()
now warns if there is a variable that may need reverse coding. This is triggered by a negative correlation value.runLinking(method = "FIXEDPAR")
was not working when the anchor instrument ID was not 1 in item map.runLinking(method = "FIXEDPAR")
was not working when the anchor and target instruments had different numbers of categories in response data.runFrequency()
was not sorting categories correctly when the number of categories was 10 or above.runCalibration(fixedpar = TRUE)
was not reading anchor parameters correctly when an integer value existed in anchor parameters.loadData()
now sanitizes input data when a data frame is supplied.runLinking()
now supports method = 'CPFIXEDDIM'
to perform two-dimensional calibration, for use in performing calibrated projection (Thissen et al., 2015). The difference with method = 'CP'
is that 'CPFIXEDDIM'
constrains the mean and the variance of the latent anchor dimension, instead of constraining anchor item parameters. For this purpose, a unidimensional fixed parameter calibration using only the anchor response data is performed to obtain the mean and the variance.getRSSS()
for computing a single raw-score to standard-score table is now exposed.getResponse()
for extracting scale-wise response data from a PROsetta_data

now supports method = 'CP'

now supports method = 'CPLA'
to perform two-dimensional calibration, for use in performing linear approximation of calibrated projection (Thissen et al., 2015).runRSSS()
now performs two-dimensional Lord-Wingersky recursion with numerical integration, when the output from runLinking(method = 'CP')
is supplied.runRSSS()
now performs linear approximation of calibrated projection, when the output from runLinking(method = 'CPLA')
is supplied.PROsetta()
now supports calibrated projection and its linear approximation.runEquateObserved(type_to = "theta")

now checks for a valid @scale_id

now returns thetas in addition to T-scores, and also expected scores in each scale.runEquateObserved()
now has type_to
