PROsetta 0.3.5
runRSSS()
output now includes linear approximation betas when the CPLA
method is used.
runLinking()
output now includes the latent mean and variance when the FIXEDPAR
method is used.
runCalibration()
, runLinking()
, runEquateObserved()
, getCompleteData()
gains verbose
argument for printing status messages. Status messages that were used to be printed in previous versions are now suppressed by default.
PROsetta 0.3.4
- Removed unused columns (
min_score
, reverse
, scores
) 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.
PROsetta 0.3.2
- Fixed where
runLinking(method = "FIXEDPAR")
was not working when the anchor instrument ID was not 1 in item map.
- Fixed where
runLinking(method = "FIXEDPAR")
was not working when the anchor and target instruments had different numbers of categories in response data.
- Fixed where
runFrequency()
was not sorting categories correctly when the number of categories was 10 or above.
PROsetta 0.3.1
Bug fixes
- Fixed where
runCalibration(fixedpar = TRUE)
was not reading anchor parameters correctly when an integer value existed in anchor parameters.
- Fixed where item parameters for dichotomous items were triggering an error while being parsed.
- For compatibility with R < 4.0,
loadData()
now sanitizes input data when a data frame is supplied.
PROsetta 0.3.0
New features
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.
PROsetta 0.2.1
QoL updates
- Added
getResponse()
for extracting scale-wise response data from a PROsetta_data
object.
- Added
getItemNames()
for extracting scale-wise item names from a PROsetta_data
object.
PROsetta 0.2.0
New features
runLinking()
now supports method = 'CP'
to perform two-dimensional calibration, for use in performing calibrated projection (Thissen et al., 2011).
runLinking()
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.
- Shiny application
PROsetta()
now supports calibrated projection and its linear approximation.
Bug fixes
runEquateObserved(type_to = "theta")
now works.
loadData()
now checks for a valid @scale_id
.
PROsetta 0.1.4
Structural changes
PROsetta_config
class and createConfig()
are now deprecated. The functionalities are merged to PROsetta_data
class and loadData()
.
run*()
functions now require PROsetta_data
objects instead of PROsetta_config
objects.
runLinking()
now has method
argument to specify the type of linking to perform. Accepts MM
, MS
, HB
, SL
, and FIXEDPAR
.
Updates
runLinking()
is now capable of performing fixed calibration.
runCalibration()
now performs free calibration by default.
runCalibration()
and runLinking()
now errors when iteration limit is reached, without returning results.
runRSSS()
now returns thetas in addition to T-scores, and also expected scores in each scale.
runEquateObserved()
now has type_to
argument to specify direct raw -> T-score equating or regular raw -> raw equating.
- Functions are now more verbose.
- Added PROMIS Depression - CES-D linking dataset
data_dep
.
- Added
plot()
for drawing raw score distribution histograms.
- Added
plotInfo()
for drawing scale information plots.
- Added several helper functions.
- Made cosmetic improvements on Shiny app.
Bug fixes
- Fixed where Shiny app was displaying SL method linear transformation constants regardless of specified linking method.
PROsetta 0.0.4
- Added
scalewise
argument to runClassical()
and runCFA()
. When TRUE
, analysis is performed for each scale.
runEquateObserved()
now removes missing values to produce correct raw sums.
loadData()
now retains missing values.
PROsetta 0.0.3
loadData()
now removes missing values.
