D-scoring Method of Measurement presents a unified framework of classical and latent measurement referred to as D-scoring method of measurement (DSM). Provided are detailed descriptions of DSM procedures and illustrative examples of how to apply the DSM in various scenarios of measurement. The DSM is designed to combine merits of the traditional CTT and IRT for the purpose of transparency, ease of interpretations, computational simplicity of test scoring and scaling, and practical efficiency, particularly in large-scale assessments. Through detailed descriptions of DSM procedures, this book shows how practical applications of such procedures are facilitated by the inclusion of operationalized guidance for their execution using the computer program DELTA for DSM-based scoring, equating, and item analysis of test data. In doing so, the book shows how DSM procedures can be readily translated into computer source codes for other popular software packages such as R. D-scoring Method of Measurement equips researchers and practitioners in the field of educational and psychological measurement with a comprehensive understanding of the DSM as a unified framework of classical and latent scoring, equating, and psychometric analysis.

In Software Project Estimation, author Dimitre Dimitrov extrapolates upon the most crucial steps in accurately and meaningfully forecasting the timeline and specs of promised deliverables to clients. A client's positive experience with project delivery and implementation is a software organization's calling card in the industry. The lifespan of a software project-from ideation to final installation-introduces dozens of potential pitfalls for a company's track record, earnings, and overall team morale. However, these "pitfalls" are also opportunities to showcase strengths and to improve an organization's product quality, and it all starts with project estimation. Reliable forecasting continues to present a challenge to even the most veteran teams and software development organizations. Dimitrov sets out to ease these common difficulties with invaluable methodology improvements and helpful visuals from his years of industry experience. Project managers-through harnessing the power of hard data and statistics-have a new world of impactful forecasting at their fingertips. This approach brings security, predictability, and motivation within the team, while simultaneously greatly benefiting client trust and relationships. Software Project Estimation clarifies the common misunderstandings that materialize between making a promise, making a plan, and building a forecast backed by data. Learn how to create an intelligent software project forecast and use it to make timely decisions, apply measured project control, and confidently steer your ship toward your goals with Software Project Estimation. What You Will Learn Concepts related to software estimation, forecasting, and project control Ways in which you can positively affect the relationships among team members working on a software delivery project How to apply this forecasting model, within both agile and waterfall teams who have adopted sound engineering practices Who This Book is For This book is directly relevant to the roles of scrum masters and project managers, and provides practical tools for intelligent project control. The book is also valuable for business people who want insight into the type of problems that delivery teams face, and for programmers and other delivery team members who want to gain an understanding of the project manager's day-to-day challenges.
