start by talking about a few examples of supervised learning problems. Suppose we have a dataset giving the living areas and prices of 47 houses from Portland, Oregon: Living area (feet2 ) 2104 1600 2400 1416 3000 . . . We can plot this data: housing prices 1000 900 800 700 price (in $1000) 600 500 400...
It covers the graphical user interface of S-PLUS and introduces the underlying S language. The main goal of this book is to get you started and the best way to do that is to use this book interactively during an S-PLUS session. After reading this book you should be able to import data into the system...
Log-Linear Models Brief History Until the late 1960’s, two-way contingency tables were typically analyzed by calculating chi-square values testing the hypothesis of independence. When tables consisted of more than two variables, researchers used to compute the chi-squares for two-way tables...
can be many things: units produced, units sold, calls made, cars rented, pages printed, or hours worked. For example, making a wedding cake requires one kilo of flour for every order. As the number of cake orders increase, the number of kilos of flour that is consumed also increases, and vice versa. ...

Multiple linear regression efforts to model the relationship between two or more explanatory variables and a response variable by fitting a linear equation to observed data. Every value of the independent variable x is associated with a value of the dependent variable y. The population regression line for...
Chapter 2: Linear Functions Chapter one was a window that gave us a peek into the entire course. Our goal was to understand the basic structure of functions and function notation, the toolkit functions, domain and range, how to recognize and understand composition and transformations of functions...

Also, the practical applicability of Bayesian methods has been greatly enhanced through the development of a range of approximate inference algorithms such as variational Bayes and expectation propagation. Similarly, new models based...
