formatOutput
is a function for formatting the output examinee

of the function maat
for analysis.
formatOutput(examinee_list, digits = 3)
examinee_list |
the output from |
digits |
digits to round theta values. (default = 3) |
a data frame containing:
p_ID
: the person ID.
test_phase_ID
: the module position. If we have 3 tests with 2 phases in each test then the range of test_phase_ID is 1 to 6.
initial_grade
: the initial grade of the person.
final_grade
: the final grade of the person after completing all modules.
grade_ID
: the grade at the module position.
phase_ID
: the phase at the module position.
test_ID
: the test at the module position.
module_ID
: the module ID at the module position.
final_theta_est
: the grand final estimated θ after completing all tests.
final_SE_est
: the standard error of grand final estimated θ after completing all tests.
theta_by_phase
: the final estimated θ after completing each phase.
SE_by_phase
: the standard error of final estimated θ after completing each phase.
combined
: whether items were combined with the previous phase to obtain the theta estimate.
true_theta
: the true θ in each module position.
item_ID
: the item IDs of administered items.
ncat
: the number of categories of administered items.
IRT_model
: the IRT models of administered items.
item_par_1
: the first item parameter of each administered item (e.g., for 1PL, this is item difficulty)
item_par_2
: the second item parameter of each administered item (e.g., for 1PL, this is 'NA')
item_resp
: the item response on each administered item.
momentary_theta
: the momentary (interim) θ estimate obtained after each item administration in CAT engine.
momentary_SE
: the standard error of momentary (interim) θ estimate obtained after each item administration in CAT engine.
