diagnosis: A function to plot model diagnostics
In jvcasillas/ds4ling: Datasets and Functions developed for SPAN658: Data Science for Linguists
diagnosis R Documentation
A function to plot model diagnostics
Description
This function generates a series of plots that can be used to check some
model assumptions in linear models.
Usage
diagnosis(mod)
Arguments
mod
A model object
diagnosis
A function for plotting model diagnostics
Details
The left panel shows residuals as a function of fitted values and is useful
for checking homoskedasticity.
The middle panel plots a histogram of the residuals with a vertical
discontinuous line that represents the mean.
The right panel provides a qq-plot of the residuals.
Examples
mod1 <- lm(mpg ~ drat, data = mtcars)
diagnosis(mod1)
