Fake Data for a Logistic Regression

Description

This is a simple fake data set to illustrate a logistic regression.

Usage

fakeLogit

Format

A data frame with 10000 observations on the following 2 variables.

x

a five-item functionally ordered categorical variable

y

a binary variable that is either 0 or 1

Details

The data are generated such that the outcome y is a logistic function of the x variable and come from a rbinom() call. The estimated natural logged odds of y when x is 0 is -2.8. Each unit increase in x is simulated to increase the natural logged odds of y by 1.4. This example is very much patterned off a similar fake data set that Pollock (2012) uses to teach about logistic regression. In his case, x is a stand-in for hypothetical education categories and y is whether this fake person voted or not.
