Changelog

gsedscripts 0.18.0

• Updates scripts/models/293_0.R to use DIF tabulation function and explore Yen’s Q3 method for exploring dimensionality
• Updates scripts/models/lf_155_0.R to feature newer functions and to compact code
• Adds scripts/DIF_demo_2groups.R to shows how to use the difR package in the SMOCC data for testing 2-group DIF with MH and logistic regression methods
• Adds calculate_DIF_table() for testing DIF

gsedscripts 0.17.0

• Substantial update 293_0 script
  • better stepwise approach
  • use of new functions to reduce copies
  • add item deletion of rare categories
  • add code to test D-score - logit alignment
  • check anchors
  • graph item and person fit
  • add tests for DIF by cohort
• Generalizes make_wide() to provide more records for analysis

gsedscripts 0.16.0

• Updates function update_required_packages() to automate modelling scripts
• Adds some dependencies into Suggests

gsedscripts 0.15.0

• Adds function update_required_packages() to automate modelling scripts
• Adds function calculate_administrative() for deriving standard administrative variables
• Adds function make_wide() to combine SF, LF and BSID data from the first observation period onto one record per child
• Adds a script inst/scripts/compare_domain_taus_293.R to inspect the overlap between three streams of the LF a as way to informally inspect the uni-dimensionality of the LF. Used for the July 2024 version of the phase1 paper.
• Adds a scripts inst/scripts/extract_equate_table.R to extract the equate table to compare keys gsed1912 and gsed2406. Used for the July 2024 version of the phase1 paper.

gsedscripts 0.14.0

• Adds Rmd/20240802_logit.Rmd to demonstrate that logit and D-score scales are consistent for LF and SF, but not for other instruments
• Adds new procedure inst/script/models/by3_extension.R to link BSID-III under fixing SF/LF tau estimates to those in model 293_0, leading to consistent logit and D-score scale for BSID-III

gsedscripts 0.13.0

• Perform updates of model 293_0 using additional LF data for BGD

gsedscripts 0.12.0

• Replaces fit_phase1_healthy_reference.R by fit_preliminary_standards.R

gsedscripts 0.11.0

• Adds a new fuzzymatching method to inst/scripts/counts.R and inst/scripts/293_0.R that takes only the first LF, SF and BSID before matching. As a result, each row corresponds to a unique subjid (child). This does not use all data, but is much easier to explain and report. The impact of the method on the item difficulty estimates is negligible (r > 0.99).

gsedscripts 0.10.0

• Adds script inst/scripts/fit_phase1_healthy_references.R to calculate new healthy references for the GSED key
• Copies code for creating Dutch references for the GSED key into file inst/scripts/fit_phase1_dutch_references.R

gsedscripts 0.9.0

• Extends script inst/scripts/fit_models.R a refit using dscore 1.8.8
• Adds script inst/scripts/compare_algorithm.R to compare models “20221201_remodel/293_0” and “20240601/293_0” using dscore 1.8.8
• Adds script inst/scripts/compare_models.R to compare models “20221201_remodel/293_0” and “20240601/293_0” using the dscore 1.8.8
• Extends script inst/scripts/fit_phase1_references.R with calculation of the healthy subsample references from the GSED key
• Extends script inst/scripts/fit_phase1_references.R with calculation of the Dutch references from the GSED key

gsedscripts 0.8.1

• Changes path in source scripts for GSED SF and BSID so that it will run from any directory, as long as the R packages dmetric and gsedscript are installed on the user’s machine.

gsedscripts 0.8.0

• Adds source scripts for document that explain scoring GSED LF and GSED SF

gsedscripts 0.7.0

• Make scripts better useable as external call

gsedscripts 0.6.0

• Updates modeling scripts
• Updates reports that documents actions taken to solve LF item order problem

gsedscripts 0.5.0

• Adds document to log actions taken to solve the LF item order problem
• Updates data reading scripts assemble_data.R and edit_data.R

gsedscripts 0.4.0

• Adds inst/scripts/counts.R to produces basic counts on LF, SF and BSID

gsedscripts 0.3.0

• Adds key update and scoring Rmd’s for reporting
• Adds scripts/export_gsed_sample.R which draws 10 sample cases
• Moves .txt files to ../export
• Moves .pdf files to ../plots

gsedscripts 0.2.0

• Added a NEWS.md file to track changes to the package.
