- Adds
calculate_sample_size()to accounts for measurement error - Makes
calculate_dmodel()work with a 2-length numeric vector
- Reverts
gsed4-->gsed3incalculate_dmodel()andplot_tau_contrast(), so now all code uses the gsed3 lexicon - Moves
calculate_DIF_classification()andcalculate_DIF_table()from gsedscripts to the dfine package - Adds
difRdependency - Reformats source files
- Adds
dazandshow_smootharguments toplot_d_a_cohort() - Adapt some routines to work with
gsed4lexicon for better integration with published test materials
- Adds
plot_d_a_cohort()andcalculate_cohort()
- Improves
NULLhandling ofplot_pass()arguments
- Replaces
plot_p_a_item(),plot_p_a_one_item()andplot_p_d_item()byplot_pass()
- Adds
plot_tau_constrast()to generate an interactiveplotlyfigure to compare two sets of tau estimates - Adds a
transform = "auto"option to thecalculate_dmodel()arguments
- Repairs bug in
plot_p_a_one_item()to allow for bothx_var = "d"andx_var = "a" - Adds built-in color palettes and
get_palette()function to retrieve them
- Adds
plot_p_d_item()for plotting pass curves against ability
- Moves
scripts/plot_p_a.Rto thegsedscriptspackage
- Adds
scripts/plot_p_a.Rto plot the passing rates by age for the -still provisional- GSED phase 1 & 2 data - Adds functions plot_p_a_item() and plot_p_a_one_item() to plot passing rates per items by a continuous variable
- Adds new function
calculate_dmodel()which works with both long and wide data - Adds
item_var,reponse_var,ability_varto list returned fromrasch() - Makes 0/1 range checks faster in
rasch()
- Add the
rasch()function to fit Rasch model with 1) item equating, 2) beta fixing and 3) pairs calculation
