A list of n+1 elements, with n the number of dimensions in the analysis. Each element is a data frame, whose name correponds to the name of the dimension the values belongs to. All data frames except the last one give the transformation of each possible raw score to the WLE or MLE score including its standard error. First column in each data frame contains the raw score, second column the transformed WLE or MLE score, third columns its standard error. The last element of the list give some sparse information about the model specifications.
