The New and Improved Two-Sample t Test
TL;DR: It is found that a transformation for skewness combined with a bootstrap method improves Type I error control and probability coverage even if sample sizes are small.
Journal ArticleDOI
Does interaction between TQM practices and knowledge management processes enhance the innovation performance
TL;DR: In this paper, the authors investigate the effect of applying total quality management (TQM) on enhancing knowledge management processes and examine the relationship between knowledge management and innovation performance in the Malaysian manufacturing sector.
Journal ArticleDOI
A review on the manufacturing defects of complex-shaped laminate in aircraft composite structures
TL;DR: In this paper, a review on the contribution of the processing parameters towards the manufacturing defects of the aircraft complex-shaped laminate is critically presented, which included the effects of the parameters on the defect formation during the sub-processes involved.
Journal ArticleDOI
Trimming, Transforming Statistics, And Bootstrapping: Circumventing the Biasing Effects Of Heterescedasticity And Nonnormality
TL;DR: In this paper, a preliminary test for symmetry which determines whether data should be trimmed symmetrically or asymmetrically, two different transformations to eliminate skewness, and the accuracy of assessing statistical significance with a bootstrap methodology was examined.
Sensitivity of normality tests to non-normal data
TL;DR: In this paper, the authors determined the sample sizes at which the Kolmogorov-Smirnov test, Anderson-Darling test, Cramer-von Mises test, and Shapiro-Wilk test would indicate that the data is not normal.
