The locally most powerful (LMP) tests of the hypothesis H : 6 = 6Q against one-sided as well as two-sided alternatives are compared with several competitive tests, as the likelihood ratio tests, the Wald-type tests and the Rao score tests, for several distribution shapes and for location, shape and vector parameters. A simulation study confirms the importance of the condition of local unbiasedn...

The design of hardware systems is a challenging and errorprone task, where a signifcant portion of the effort is spent for testing and verification. Usually testing and verification are applied as a post-process to the implementation. Meanwhile, for the development of software, testfirst approaches such as test driven development (TDD) have become increasingly important. In this paper, we propo...

One of the hardest problems in digital circuit design is test pattern generation for a complex device. This is difficult in part because it requires reasoning about how to control a device whose behavior can be extremely complex. Knowledge of the specific operations that the device was designed to perform can help solve this problem. The key observation is that a device’s designed behavior is o...

Measures of intelligence were collected in 209 twin pairs at 5, 7, 10, and 12 years of age, as part of a longitudinal project on intelligence, brain function, and behavioral problems. Intelligence was measured at 5, 7, and 10 years of age with the RAKIT, a well-known Dutch intelligence test, consisting of 6 subscales. At 12 years of age, the complete WISC-R was administered (12 subscales). Both...

Conation has been defined as the ability to focus and maintain intellectual energy over time. Prior research has shown that conation contributes to the magnitude of differences in test scores among brain-damaged and non-brain-damaged examinees. The purpose of the current investigation was to determine if conation might similarly account for differences in test scores among performance valid and...
