pairs.logitModel: S3 Pairs Method for logitModel Objects

In mr-avila/logitModel: Simple Alternative to Logit Modelling in R

Description

This internal function defines a pairs method for an object of logitModel class. The main idea is to plot all explanatory variables agaist the response variable of the model in order to quickly assess the influence of each one.

Usage

## S3 method for class 'logitModel'
pairs(model, nRow, single = FALSE, col, ask, ...)

Arguments

model	an object of class logitModel.
nRow	optional numeric vector indicating the number of rows the overall plot should have.
single	boolean to indicate whether each variable should be plotted against the response variable individually.

Examples

set.seed(42)
n <- 100
dummies <- sample(LETTERS[1:5], n, replace = TRUE)
X1 <- rnorm(n); X2 <- rnorm(n)
points <- 2 * X1 - 3 * X2
y <- rbinom(n, 1, exp(points) / (1 + exp(points)))
df <- as.data.frame(cbind(b2 = X1, b3 = X2))
myFitD <- logitModel(y ~ X1 + X2 + dummies)
pairs(myFitD)
pairs(myFitD, single = TRUE)
