Statistical Tests, Tests Of Significance, And Tests Of A Hypothesis Using Excel, David A. Heiser

Journal of Modern Applied Statistical Methods

Microsoft’s spreadsheet program Excel has many statistical functions and routines. Over the years there have been criticisms about the inaccuracies of these functions and routines (see McCullough 1998, 1999). This article reviews some of these statistical methods used to test for differences between two samples. In practice, the analysis is done by a software program and often with the actual method used unknown. The user has to select the method and variations to be used, without full knowledge of just what calculations are used. Usually there is no convenient trace back to textbook explanations. This article describes the Excel algorithm …

Robust Confidence Intervals For Effect Size In The Two-Group Case, H. J. Keselman, James Algina, Katherine Fradette

Journal of Modern Applied Statistical Methods

The probability coverage of intervals involving robust estimates of effect size based on seven procedures was compared for asymmetrically trimming data in an independent two-groups design, and a method that symmetrically trims the data. Four conditions were varied: (a) percentage of trimming, (b) type of nonnormal population distribution, (c) population effect size, and (d) sample size. Results indicated that coverage probabilities were generally well controlled under the conditions of nonnormality. The symmetric trimming method provided excellent probability coverage. Recommendations are provided.

Testing For Aptitude-Treatment Interactions In Analysis Of Covariance And Randomized Block Designs Under Assumption Violations, Tim Moses, Alan Klockars

Journal of Modern Applied Statistical Methods

This study compared the robustness of two analysis strategies designed to detect Aptitude-Treatment Interactions to two of their similarly-held assumptions, normality and residual variance homogeneity. The analysis strategies were the test of slope differences in analysis of covariance and the test of the Block-by- Treatment interaction in randomized block analysis of variance. With equal sample sizes in the treatment groups the results showed that residual variance heterogeneity has little effect on either strategy but nonnormality makes the test of slope differences liberal and the test of the Block-by-Treatment interaction conservative. With unequal sample sizes in the treatment groups the often-reported …

Specifying And Checking Method Call Sequences Of Java Programs, Yoonsik Cheon, Ashaveena Perumandla

Departmental Technical Reports (CS)

In a pre and postconditions-style specification, it is difficult to specify the allowed sequences of method calls, referred to as protocols. The protocols are essential properties of reusable object-oriented classes and application frameworks, and the approaches based on the pre and postconditions, such as design by contracts (DBC) and formal behavioral interface specification languages (BISL), are being accepted as a practical and effective tool for describing precise interfaces of (reusable) program modules. We propose a simple extension to the Java Modeling Language (JML), a BISL for Java, to specify protocol properties in an intuitive and concise manner. The key idea …

Improving After-The-Fact Tracing And Mapping: Supporting Software Quality Predictions, Jane Huffman Hayes, Alex Dekhtyar, Senthil Sundaram

Computer Science and Software Engineering

The software engineering industry undertakes many activities that require generating and using mappings. Companies develop knowledge bases to capture corporate expertise and possibly proprietary information. Software developers build traceability matrices to demonstrate that their designs satisfy the requirements. Proposal managers map customers' statements of work to individual sections of companies' proposals to prove compliance. Systems engineers authoring interface specifications record design rationales as they make relevant decisions. We developed an approach to tracing and mapping that aims to use fully automated information retrieval techniques, and we implemented our approach in a tool called RETRO (requirements tracing on target).

The Archway Project: Architecture For Research In Computing For Humanities Through Research, Teaching, And Learning, Kevin Kiernan, Jerzy W. Jaromczyk, Alex Dekhtyar, Dorothy Carr Porter, Kenneth Hawley, Sandeep Bodapati, Ionut E. Iacob

Computer Science and Software Engineering

An unusual alliance called the ARCHway Project is developing an Edition Production Technology (EPT), a technological infrastructure for collaborative research, teaching, and learning between computer scientists and specialists in Old English. Our goal is to identify and solve problems of mutual importance in building image-based electronic editions of significant cultural materials. The EPT will allow us to implement and integrate both new and already available software applications, to construct a digital library of previously unedited Old English manuscripts as a testbed for our solutions, and to distribute the digital library to the public. This paper introduces some of the tools …

Role Of Higher-"Mode" Pushover Analyses In Seismic Analysis Of Buildings, Rakesh K. Goel, Anil K. Chopra

Civil and Environmental Engineering

The role of higher-“mode” pushover analyses in seismic analysis of buildings is examined in this paper. It is demonstrated that the higher-“mode” pushover curves reveal plastic hinge mechanisms that are not detected by the first-“mode” or other FEMA-356 force distributions, but these purely local mechanisms are not likely to develop during realistic ground motions in an otherwise regular building without a soft and/or weak story. Furthermore, the conditions necessary for “reversal” of a higher-“mode” pushover curve are examined. It is shown that “reversal” in a higher-“mode” pushover curve occurs after formation of a mechanism if the resultant force above the …

Performance Of Binary-Encounter-Bethe (Beb) Theory For Electron-Impact Ionization Cross Sections Of Molecules Containing Heavy Elements (Z > 10), Gregory E. Scott, Karl K. Irikura

Chemistry and Biochemistry

The binary-encounter-Bethe (BEB) theory developed by Kim and coworkers has been successful for computing electron-impact ionization cross sections of many molecules. However, some recent publications have stated that BEB theory performs poorly for molecules that contain heavier elements such as chlorine and sulfur. We have found that the BEB calculations in those publications were performed incorrectly. When performed correctly, BEB predictions are as good for heavy-element molecules as for light-element molecules. We recommended recently that an alternative, less-confusing procedure be used for molecules that contain heavier elements. The alternative procedure, based upon effective core potentials (ECPs), does not require explicit …

Optimal Adaptation In Autonomic Web Processes With Inter-Service Dependencies, Kunal Verma, Prashant Doshi, Karthik Gomadam, John A. Miller, Amit P. Sheth

Kno.e.sis Publications

We present methods for optimally adapting Web processes to exogenous events while preserving inter-service dependencies. For example, in a supply chain process, orders placed by the manufacturer may get delayed in arriving. In response to this event, the manufacturer has the choice of either waiting out the delay or changing the supplier.

The Screech Owl Reasoner - Scalable Approximate Abox Reasoning With Owl, Pascal Hitzler, Denny Vrandecic

Computer Science and Engineering Faculty Publications

We present a preliminary version of the approximate OWL reasoning system SCREECH. It builds on the KAON2 system and performs OWL ABox reasoning in an approximate manner. It trades soundness of reasoning for efficiency, with resulting polynomial worst-case data complexity. It has been developed for use in time-critical applications where quick response time is more important than a full guarantee of correctness of answers. The theoretical background for the system is explained in [Hitzler and Vrandecic, 2005] and is being presented at the conference.

Chimpanzee Theory Of Mind: Looking In All The Wrong Places?, Kristin Andrews

Sentience Collection

I respond to an argument presented by Daniel Povinelli and Jennifer Vonk that the current generation of experiments on chimpanzee theory of mind cannot decide whether chimpanzees have the ability to reason about mental states. I argue that Povinelli and Vonk’s proposed experiment is subject to their own criticisms and that there should be a more radical shift away from experiments that ask subjects to predict behavior. Further, I argue that Povinelli and Vonk’s theoretical commitments should lead them to accept this new approach, and that experiments which offer subjects the opportunity to look for explanations for anomalous behavior should …

School Reform Strategies And Normative Expectations For Democratic Leadership In The Superintendency, George J. Petersen, Theodore J. Kowalski

Graduate Studies in Education

The ability of the superintendent to communicate ethical leadership to the community and demonstrate a positive relationship with the board president and the board of education has considerable influence on communities’ perceptions of the quality of educational programs and the academic achievement of children. This investigation employed social capital theory as a conceptual lens to investigate these relationships. Our findings suggest that district superintendents tread a fragile bridge where the sustainability of their leadership is dependent upon their mastery of the interplay among ethics, advocacy, and community relations.
