It produces ItemStats file (for both old test and new test) and equating table. Plots of liking item score and total score distribution are also developed.

|
MainPath |
The folder where the response files are stored in |
XName |
Name of the X test (without "_Listening" or "_Reading") |
n_demoX |
Number of demographic variables in X. Default value is 6. |
n_demoY |
Number of demographic variables in Y. |
DNS_X_r |
Vector of not score items in X reading test. Default is NULL. |
DNS_X_l |
Vector of not score items in X listening test. |
DNS_Y_r |
Vector of not score items in Y reading test. |
DNS_Y_l |
Vector of not score items in Y listening test. |
keychange_X_r |
List of key change for X reading test. Default is NULL. The first element is the item index, the rest are the keys. |
keychange_X_l |
List of key change for X listening test. |
keychange_Y_r |
List of key change for Y reading test. |
keychange_Y_l |
List of key change for Y listening test. |
equate_coef_l |
List of Tucker linear equating coefficience for Listening. First element is intercept, second is slope. e.g. c_2015 equates 2016 test score to 2015. When using this function, just fill in proper equating coefficience. |
equate_coef_r |
List of Tucker linear equating coefficience for Reading. |
Xpath |
Path of the old response file is stored in |
Ypath |
Path of the new response file is stored in |
XName |
Name of the Y test |
Stats for both forms of test and the equating table.
