Minor edits in the documentation of cdcat() and fixed typos for
cdcat.summary() output for itemSelect = ‘GNPS’ or ‘NPS’
applications
cdcat 1.0.5:
The general non-parametric method for CD-CAT was included in
cdcat()
The cdcat.summary() function can now be also used without providing
the argument att()
cdcat 1.0.4:
Some examples removed from gen.data()
Fixed attribute labels in att.plot()
Fixed a bug for LR.2step() where the function stopped if the
computations resulted in NA
cdcat 1.0.3:
cdcat.summary: Minor modifications in the plots
gen.itembank: Two additional arguments incorporated (gs.parm and
catprob.parm) to allow for more targeted manipulation of the quality of
the item bank
cdcat: New arguments included for specification of the starting rule
(startK and startRule), item exposure control (itemExposurecontrol, b,
and maxr), and the inclusion of additional constraints (itemConstraint
and constraint.args$ATTRIBUTEc)
helper: Functions updated to accommodate the above-mentioned
modifications
cdcat 1.0.2:
Fixed a bug for cdcat() when ItemSelect = “JSD”
Fixed a bug for cdcat() when ItemSelect = “PWKL”
Minor modification of cdcat() for gathering the information
(Q-matrix)
cdcat 1.0.1:
Addressed the noLD unit test issues in the previous version
cdcat 1.0.0:
DESCRIPTION:
version and date updated
P. Nájera listed as a co-author
package dependencies updated
att.plot:
CDM package accepted
nonparametric CD-CAT accepted
k argument included for selecting the attributes to be plotted. If k
= NULL (by default), all attributes are plotted
color has been added to the plot: red = non-mastered, green =
mastered, blue = unclassified
cdcat:
CDM package accepted
several item selection rules included: GDI, JSD, MPWKL, PWKL, NPS,
random (argument itemSelect)
nonparametric CD-CAT included (itemSelect = “NPS”)
different arguments available: gate, pseudo.prob, w.type, and seed
(argument NPS.args). pseudo.prob and w.type are experimental
some arguments needed to be modified / included (e.g., Q is required
with nonparametric CD-CAT)
parallelization included (argument n.cores)
some warning / error messages included
information regarding multiple modes (for ML and MAP) included in
the output
i.print is a deprecated argument. When parallelizing, no information
is printed
updated information and references
new example for the nonparametric CD-CAT included
examples updated
cdcat.summary:
major update
item exposure information included
optional label argument included (in case two objects share
model)
CDM package accepted
nonparametric CD-CAT accepted
plots improved (e.g., without secondary grids)
violin plot for variable length CD-CAT improved (e.g., geom_dotplot
instead of geom_jitter, x axis labels removed)
cdcat.comp:
function removed. cdcat.comp is now included in cdcat.summary
gen.data:
new function to simulate data
gen.itembank:
major update
data generation under different CDMs using the GDINA::simGDINA
function
additional specifications when creating a Q-matrix included
LR2step:
example updated
CDM package accepted
error when K^*j = 4 fixed
p.adjust.methods method and alpha.level arguments included
new output included LR2.adjp and models.adjp
sim180combination,
180DINA, sim180GDINA
updated
helper:
all functions required for cdcat and gen.itembank functions
included
