I am not sure, I used the model which is offered by this web, but I can't get the result as your paper.
the variable 'er_abs' represents the final error in your inferenceCFSS program, in this vector, from 1 to 330 represents the HELEN test results, the mean value is 13.7559, form 331 to 554 represents the LFPW test results, the mean value is 3.5879, and from 555 to 689 represents the IBUG test results, the mean value is 7.7492. I wonder to know why my results is not the same as yours. Thank you for your explanation.
