Testing the Validity of Kinship Microsimulation: An Update
Computer microsimulation is capable of generating detailed reconstructions and forecasts of the numbers of living kin that members of a population have. The available detail, specificity, and consistency of vital rates for the past and the accuracy of vital rates projected for the future necessarily limit the accuracy of the kinship estimates that can be produced. This study updates the validit...
متن کاملEcological validity of performance validity testing.
Performance validity tests (PVTs) have been shown to relate to neuropsychological performance, but no studies have looked at the ecological validity of these measures. Data from 131 veterans with a history of mild traumatic brain injury from a multicenter Veterans Administration consortium were examined to determine the relation between scores on a self-report version of the Mayo-Portland Adapt...
متن کاملTesting the validity of erythema detection algorithms.
Dermatology has quantified skin color for monitoring progress of treatments. The most common and effective means of erythema detection is visual inspection of the skin. However, for people with darkly pigmented skin, erythema can be masked by melanin. Tissue Reflectance Spectroscopy (TRS) is a noninvasive method of quantifying skin color. Most commonly, TRS quantifies erythema caused by cosmeti...
متن کاملTesting the Ecological Validity of Repetitive Speech
Can one trust experiments conducted with repetitive speech to represent normal language behaviour? We compare the spectra of repetitive productions of phrases with the same phrases read from a randomised list. We use a data-driven spectral distortion measure that is trained to respond to linguistically relevant differences: it is based on a classifier that separates sounds into linguistically e...
متن کاملDesigning, Fabricating, and Testing the Validity and Reliability of the Digital Headband for Cervical Proprioception Assessment: A Descriptive Study
Background and Objectives: Accuracy of proprioceptive input plays an important role in cervical motor control. Several methods have been used to evaluate the accuracy of proprioceptive input as a factor of cervical injury prevention or rehabilitation. The aim of this study was to introduce a new tool for evaluating the accuracy of cervical proprioception and determine its validity and reliabili...
