Nominal analysis of "variance".
Nominal responses are the natural way for people to report actions or opinions. Because nominal responses do not generate numerical data, they have been underutilized in behavioral research. On those occasions in which nominal responses are elicited, the responses are customarily aggregated over people or trials so that large-sample statistics can be employed. A new analysis is proposed that di...
متن کاملOn Decidability of Nominal Subtyping with Variance
We investigate the algorithmics of subtyping in the presence of nominal inheritance and variance for generic types, as found in Java 5, Scala 2.0, and the .NET 2.0 Intermediate Language. We prove that the general problem is undecidable and characterize three different decidable fragments. From the latter, we conjecture that undecidability critically depends on the combination of three features ...
متن کاملA measure of variance for hierarchical nominal attributes
The need for measuring the dispersion of nominal categorical attributes appears in several applications, like clustering or data anonymization. For a nominal attribute whose categories can be hierarchically classified, a measure of the variance of a sample drawn from that attribute is proposed which takes the attribute’s hierarchy into account. The new measure is the reciprocal of ‘‘consanguini...
متن کاملStatistical Data Mining For Nominal Value Variance Anomaly With Visualization
A Nominal Value Variance (NVV) anomaly is an analog measurement whereby the measured value is within the “passing” range for a given test but has departed from the nominal value significantly such that a problem may exist. The occurrence of this anomaly could indicate a test implementation problem if the anomaly is occurring during Test Program Set (TPS) development. Manual discovery of a NVV a...
متن کاملPractice reduces task relevant variance modulation and forms nominal trajectory
Humans are capable of achieving complex tasks with redundant degrees of freedom. Much attention has been paid to task relevant variance modulation as an indication of online feedback control strategies to cope with motor variability. Meanwhile, it has been discussed that the brain learns internal models of environments to realize feedforward control with nominal trajectories. Here we examined t...
