categorical variable. D. Our goal is to use categorical variables to explain variation in Y, a quantitative dependent variable. 1. We need to convert the categorical variable gender into a form that “makes sense” to regression analysis. E. One way to represent a categorical variable is to code the categories 0 and 1 as follows:

Data that are counts are categorical data. A categorical variable is measured on a scale that is nominal (eg – religion) or ordinal (eg – diagnosis coded as “benign”, “suspicious”, or “malignant”). Unit 4 (Categorical Data Analysis) is an introduction to some basic methods for the

### Working with categorical data and factor variables

2[U] 26 Working with categorical data and factor variables it is an indicator variable because it denotes the truth value of the statement “the observation is in this group”. All indicator variables are categorical variables, but the opposite is not true. A categorical variable might divide the data into more than two groups.

### Data Analysis Basics: Variables and Distribution

nciph.sph.unc.edu

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

### Working with categorical data and factor variables

www.stata.com

We can use the same logic on any categorical variable that divides the data into two groups. It is a categorical variable because it identiﬁes whether an observation is a member of this or that group; it is an indicator variable because it denotes the truth value of the statement “the observation is in this group”.
