Regression with Categorical Independent Variables • How to put “male” and “female” categories in a regression equation? – Code them as indicator (dummy) variables • Two ways of making dummy variables: – Male = 1, female = 0 • Default in many programs – Male = 1, female = -1 • Default in JMP for nominal variables 12

dependent variables (factors that are changed). 2. Experiments require an experimental group (subjects exposed to the independent variable) and a control group (subjects not exposed to the independent variable). F. Unobtrusive measures involve observing social behavior of people who do not know they are being studied.
Sums of random number of random variables (random sums). Let X1;X2;X3;:::: be a sequence of independent identically distributed random variables (i.i.d. random variables), each with the same distribution, each having common mean a = E(X) and variance s2 =Var(X). Here X is a r.v. having the same distribution as Xj. The sum S =åN j=1 Xj

Rather than write “height is a function of age”, we could use the descriptive variable h to represent height and we could use the descriptive variable a to represent age. “height is a function of age” if we name the function f we write “h is f of a” or more simply h = f(a) we could instead name the function h and write
Variable Valve Timing is utilized on many of Suzuki’s high-end outboards to deliver high performance across the outboard’s full powerband while retaining the benefits that four-stroke technology provides.
