This document involves the application of a Principal Component Analysis (PCA) on the performance data of 31 students from the STID1 program, covering four coursework grades: Informatics, Algorithms, Mathematical Foundations, and Mathematical Techniques. The analysis was performed using the SAS software, focusing on interpreting statistical descriptors like means and standard deviations, building a correlation matrix, and diagonalizing it to extract eigenvalues and eigenvectors. The core findings highlight the number of axes needed for meaningful visualization, significant contributors to t...

This document provides a comprehensive guide for managing projects in various settings, emphasizing the applicability of core principles beyond technical environments. It introduces the 'CPS' method, a framework developed by the author to simplify project management concepts, based on personal research and professional experience. The guide includes detailed modules on project life cycles, planning, resource allocation, risk management, and team coordination. Furthermore, complementary training materials are suggested, such as 'Management of a Team' for human aspects and 'Design and Develop...
The document comprises two exercises focusing on privacy rights and personal data categorization. The first exercise examines a privacy breach in which a fitness center manager published a video of clients without consent, violating their right to privacy. The second exercise outlines types of personal data, distinguishing direct identifiers, indirect identifiers, and sensitive data. The analysis emphasizes the importance of maintaining confidentiality and adhering to data protection principles.
The document is an academic guide presenting HBase, a distributed, column-oriented database built on Hadoop. It systematically compares HBase to HDFS, elucidating its dynamic structuring capabilities and memory-oriented processing speeds. Furthermore, the HBase data model, structured as multidimensional tables with dynamic columns, families, timestamps, and cells, is detailed alongside its architectural components like HMaster, RegionsServers, and Zookeeper. Finally, it highlights HBase's practical applications across industries such as telecommunications and banking, while describing pract...
This textbook, now in its 9th edition, introduces econometrics as both a theoretical and applied discipline. Through detailed discussions on regression models, hypothesis violations, time series analysis, VAR, cointegration, and qualitative variable econometrics, the book offers a comprehensive approach to the subject. It systematically alternates between theoretical content and practical exercises, using software tools such as Excel, RATS, Eviews, and GRETL to enhance hands-on learning. Tailored for students and practitioners, it is a valuable resource for understanding statistical estimat...
This technical study by CGI explores the principles and mechanisms of public key cryptography and digital signatures.
