v1.8

This release is equipped to handle the calibration of a substantial number of items (100-200) by organizing them into blocks of 3-5 items each. A new function, drawdesign_allitems, has been developed to allow users to visualize the optimal calibration design for all items in a single graph. Additionally, the efficiency function now offers the ability to assess the efficiency of the optimal design in comparison to a random design for each block. Graphs for the optimal design in each block can be generated using the drawdesign function. To monitor the convergence of the optimal item calibration algorithm, convergence plots can be produced for each block using the convergenceplot function.

v1.7.1
