Chapter 4 Exploratory Data Analysis

4.2.1 Categorical data The characteristics of interest for a categorical variable are simply the range of values and the frequency (or relative frequency) of occurrence for each value. (For ordinal variables it is sometimes appropriate to treat them as quantitative vari-ables using the techniques in the second part of this section.) Therefore ...

I. POPULATIONS, VARIABLES, and DATA

A. Nominal variables are variables whose values are labels. The order of the labels may have no special significance. In the example above, “Gender” is a nominal variable whose values are “M” and “F”. Nominal variables are also called categorical variables or factors. Nominal variables may be represented by numbers.

Data Analysis Basics: Variables and Distribution

Categorical variables contain informa-tion that can be sorted into catego-ries, rather like sorting information into bins. Every piece of information belongs in one—and only one—bin. There are several types of categorical variables: ordinal, nominal, and di-chotomous or binary. An ordinal variable is any categorical

Marginal Effects Continuous Variables

Categorical variables, such as psi, can only take on two values, 0 and 1. It wouldn’t make much sense to compute how P(Y=1) would change if, say, psi changed from 0 to .6, because that cannot happen. The MEM for categorical variables therefore shows how P(Y=1) changes as the categorical variable changes from 0 to 1, holding all
