It seems clear that both age and gender have an e ect on someone’s survival, how do we come up with a model that will let us explore this relationship? Even if we set Died to 0 and Survived to 1, this isn’t something we can transform our way out of - we need something more. One way to think about the problem - we can treat Survived and Died as

Projective Geometry: A Short Introduction

Master MOSIG Introduction to Projective Geometry Chapter 1 Introduction 1.1 Objective The objective of this course is to give basic notions and intuitions on projective geometry. The interest of projective geometry arises in several visual comput-ing domains, in particular computer vision modelling and computer graphics.

A Concise Course in Algebraic Topology J. P. May

needs of algebraic topologists would include spectral sequences and an array of calculations with them. In the end, the overriding pedagogical goal has been the introduction of basic ideas and methods of thought. Our understanding of the foundations of algebraic topology has undergone sub-tle but serious changes since I began teaching this course.
