This paper proposes simple Hausman-type tests to check for bias in the log-periodogram regression of a time series believed to be long memory. The statistics are asymptotically standard normal on the null hypothesis that no bias is present, and the tests are consistent. The use of the tests in...

Generalizability theory provides an alternative and more flexible approach for construct measurement than classical measurement theory. The theory takes into account several sources of error. Generalizability studies lead to results that allow for designing measurements that optimize the...
