Histogram of model residuals

Usage

residuals_hist_plot(
  model,
  type = c("deviance", "pearson", "response", "pit", "quantile"),
  n_bins = c("sturges", "scott", "fd"),
  ylab = NULL,
  xlab = NULL,
  title = NULL,
  subtitle = NULL,
  caption = NULL,
  seed = NULL
)

Arguments

model: a fitted model. Currently only class "gam".
type: character; type of residuals to use. One of "deviance", "response", "pearson", "pit", and "quantile" residuals are allowed. "pit" uses probability integral transform (PIT) residuals, which, if the model is correct should be approximately uniformly distributed, while "quantile" transforms the PIT residuals through application of the inverse CDF of the standard normal, and therefore the quantile residuals should be approximately normally distributed (mean = 0, sd = 1) if the model is correct. PIT and quantile residuals are not yet available for most families that can be handled by gam(), but most standard families are supported, e.g. those used by glm().
n_bins: character or numeric; either the number of bins or a string indicating how to calculate the number of bins.
ylab: character or expression; the label for the y axis. If not supplied, a suitable label will be generated.
xlab: character or expression; the label for the y axis. If not supplied, a suitable label will be generated.
title: character or expression; the title for the plot. See ggplot2::labs().
subtitle: character or expression; the subtitle for the plot. See ggplot2::labs().
caption: character or expression; the plot caption. See ggplot2::labs().
seed: integer; random seed to use for PIT or quantile residuals.
