Analysis of variance (ANOVA), the workhorse analysis of experimental designs, consists of F-tests of main effects and interactions. Yet, testing, including traditional ANOVA, has been recently critiqued on a number of theoretical and practical grounds. In light of these critiques, model comparison and model selection serve as an attractive alternative. Model comparison differs from testing in t...

One of the hallmarks of statistical thinking is the importance of measuring and understanding variability. The Shewhart Control Chart, which separates special cause from common cause variation, is one of the most important tools for understanding the current state of a process. The analysis of variance (ANOVA) is another statistical tool for splitting variability into component sources. These c...

Although polymethylmethacrylate (PMMA) is widely used as a denture base material, its disadvantages include low strength and thermal conductivity. The effects on conductivity, flexural strength, diffusivity, elastic modulus of adding Al2O3 SiC powders in different volumes to PMMA were investigated. A total 60 specimens prepared 10 groups (five for the conductivity test five (n:6). immersed wate...

This research intends to evaluate the relation, aided by Brazilian Standard and statistical analysis (Kruskal-Wallis ANOVA bootstrap technique), between physical mechanical properties of Cambará-Rosa wood harvested from three different regions: Vera, Mucajaí South Rondonia. In addition, possibility estimate (regression models) in function apparent density was analyzed. Different climate soil ...

Stroke and heart disease are among the most com-mon outcomes of hypertension. Each year, disease, stroke, other cardiovascular disorders claim lives more than 877,500 people in United States, making them first fifth leading causes death, so being able to pre- dict early helps save lives. A lot research has been done reach this goal. Machine learning models mostly used for purpose. For time stud...
