Aspects on Statistical Approach of Population Homogeneity

چکیده
In this article we emphasize the manner in which this statistical indicator the variation coefficient (v) could help the inference on measurable characteristics generated by technological processes. Our interest lies upon the so-called SPCStatistical Process Control; the main result obtained is the following: if the coefficient of variation is known, then the statistical distribution of capability index is of ALPHA-type distribution (Družinin). We also put into light some links between (v) and Taguchi’s quality loss function.

متن کاملData Driven Approaches to Testing Homogeneity of Intraclass Correlation Coefficients
The test of homogeneity for intraclass correlation coefficients has been one of the active topics in statistical research. Several chi-square tests have been proposed to test the homogeneity of intraclass correlations in the past few decades. The big concern for them is that these methods are seriously biased when sample sizes are not large. In this thesis, data driven approaches are proposed t...

متن کاملA new approach for achieving excellent strain homogeneity in tubular channel angular pressing (TCAP) process
Tubular channel angular pressing (TCAP) is a recently invented novel severe plastic deformation technique for producing UFG tubes. Plastic deformation analysis using the finite element method (FEM) was carried out to investigate the effects of trapezoidal channel geometry on strain inhomogeneity index (SII), strain level and required load compared to previously used channel geometries. The resu...
