Systematic Errors in Approximations to the Standard Error of Measurement and Reliability

Kleinke, David J. (1979)
Lord’s approximation to the standard error of measurement of a test uses only n, the number of items. Millman’s is based on n and p̄, the mean difficulty. Saupe has used Lord’s approximation to derive an approximation ...

On the robustness of a class of naive estimators

Wainer, Howard; Thissen, David (1979)
A class of naive estimators of correlation was tested for robustness, accuracy, and efficiency against Pearson’s r. Tukey’s r., and Spearman’s ro. It was found that this class of estimators seems in some respects to ...

The reliability of dichotomous judgments: Unequal numbers of judges per subject

Fleiss, Joseph L.; Cuzick, Jack (1979)
Consider a reliability study in which different subjects are judged on a dichotomous trait by different sets of judges, possibly unequal in number. A kappa-like measure of reliability is proposed, its correspondence ...

Ordering power of separate versus grouped true-false tests: Interaction of type of test with knowledge levels of examinees

Hsu, Louis M. (1979)
The ordering power of an objective test was defined in terms of the probability that this test led to the correct ranking of examinees. A comparison of the relative ordering power of separate and grouped-items true-false ...

Dominance, information, and hierarchical scaling of variance space

Krus, David J.; Ceurvorst, Robert W. (1979)
A method for computation of dominance relations and for construction of their corresponding hierarchical structures is presented. It is shown that variance can be computed from the squared pairwise differences between ...
