Survival analysis uses statistics to calculate time to failure. Survival Analysis with Python takes a fresh look at this complex subject by explaining how to use the Python programming language to perform this type of analysis. As the subject itself is very mathematical and full of expressions and formulations, the book provides detailed explanations and examines practical implications. The book begins with an overview of the concepts underpinning statistical survival analysis. It then delves into Parametric models with coverage of Concept of maximum likelihood estimate (MLE) of a probability distribution parameter MLE of the survival function Common probability distributions and their analysis Analysis of exponential distribution as a survival function Analysis of Weibull distribution as a survival function Derivation of Gumbel distribution as a survival function from Weibull Non-parametric models including Kaplan-Meier (KM) estimator, a derivation of expression using MLE Fitting KM estimator with an example dataset, Python code and plotting curves Greenwood's formula and its derivation Models with covariates explaining The concept of time shift and the accelerated failure time (AFT) model Weibull-AFT model and derivation of parameters by MLE Proportional Hazard (PH) model Cox-PH model and Breslow's method Significance of covariates Selection of covariates The Python lifelines library is used for coding examples. By mapping theory to practical examples featuring datasets, this book is a hands-on tutorial as well as a handy reference.

IT projects emerge from a business need. In practice, software developers must accomplish two big things before an IT project can begin: find out what you need to do (i.e., analyse business requirements) and plan out how to do it (i.e., project management). The biggest problem in IT projects is delivering the wrong product because IT people do not understand what business people require. This practical textbook teaches computer science students how to manage and deliver IT projects by linking business and IT requirements with project management in an incremental and straightforward approach. Business Analysis, Requirements, and Project Management: A Guide for Computing Students presents an approach to analysis management that scales the business perspective. It takes a business process view of a business proposal as a model and explains how to structure a technical problem into a recognisable pattern with problem frames. It shows how to identify core transactions and model them as use cases to create a requirements table useful to designers and coders. Linked to the analysis are three management tools: the product breakdown structure (PBS), the Gantt chart, and the Kanban board. The PBS is derived in part from the problem frame. The Gantt chart emerges from the PBS and ensures the key requirements are addressed by reference to use cases. The Kanban board is especially useful in Task Driven Development, which the text covers. This textbook consists of two interleaving parts and features a single case study. Part one addresses the business and requirements perspective. The second integrates core project management approaches and explains how both requirements and management are connected. The remainder of the book is appendices, the first of which provides solutions to the exercises presented in each chapter. The second appendix puts together much of the documentation for the case study into one place. The case study presents a real-word business scenario to expose students to professional practice.

Threats to application security continue to evolve just as quickly as the systems that protect against cyber-threats. In many instances, traditional firewalls and other conventional controls can no longer get the job done. The latest line of defense is to build security features into software as it is being developed. Drawing from the author's extensive experience as a developer, Secure Software Development: Assessing and Managing Security Risks illustrates how software application security can be best, and most cost-effectively, achieved when developers monitor and regulate risks early on, integrating assessment and management into the development life cycle. This book identifies the two primary reasons for inadequate security safeguards: Development teams are not sufficiently trained to identify risks; and developers falsely believe that pre-existing perimeter security controls are adequate to protect newer software. Examining current trends, as well as problems that have plagued software security for more than a decade, this useful guide: Outlines and compares various techniques to assess, identify, and manage security risks and vulnerabilities, with step-by-step instruction on how to execute each approach Explains the fundamental terms related to the security process Elaborates on the pros and cons of each method, phase by phase, to help readers select the one that best suits their needs Despite decades of extraordinary growth in software development, many open-source, government, regulatory, and industry organizations have been slow to adopt new application safety controls, hesitant to take on the added expense. This book improves understanding of the security environment and the need for safety measures. It shows readers how to analyze relevant threats to their applications and then implement time- and money-saving techniques
