Mike’s Biostatistics Book
Michael R Dohm · Chaminade University
The lecture notes are written from my perspective on what matters in a semester-long, first course in Biostatistics: concepts, context and practical advice along with a generous introduction to general linear models. The focus is on applied statistics with reference to other data science skill sets as needed. Concepts are illustrated by examples and multiple choice questions to “test” reader comprehension.

Introduction to Game Theory: a Discovery Approach
Jennifer A. Firkins Nordstrom · Linfield College
Many colleges offer courses in quantitative reasoning for all students. One model for a quantitative reasoning course is to provide students with a single cohesive topic. Ideally, such a topic can pique the curiosity of students with wide ranging academic interests and limited mathematical background. This text is intended for use in such a course. This text may also be appropriate for a high school enrichment course.

Phase Relations in Reservoir Engineering
Michael Adewumi · The Pennsylvania State University
In this text, you will learn about phase relations as applied to oil and/or gas reservoir processes, enhanced oil recovery, gas pipeline transportation, natural gas processing and liquefaction, and other problems in petroleum production. The primary objective of the course is to apply the thermodynamics of phase equilibrium to the framework for phase behavior modeling of petroleum fluids.
