plot_predVSobs: Plot predictions vs real observations for 'pffr' models

In bauer-alex/FoSIntro: Convenience Functions for Semiparametric Function-on-Scalar Regression

Description

Plots the predictions o a function-on-scalar model fitted with pffr agains the real observations.

Usage

plot_predVSobs(model, data, yvar, yvar_label, type = "response",
  log10 = FALSE, pi_type = "none", pi_alpha = 0.05, base_size = 11,
  xlab = "yindex", ylab, main = "Prediction vs observation", ybreaks,
  ylabels, ylim = NULL, lwd = 1, legend_symbol_size = 2, ...)

Arguments

model	Function-on-scalar model fitted with pffr
data	Dataset with one row for which the predictions are to be plotted
yvar	name of the response variable in model
yvar_label	Optional label of the response variable used for plot annotation
type	"response" (default) or "link". See predict.pffr.
log10	If TRUE the predictions are shown on a log10 scale
pi_type	One of "none" (default; no uncertainty bands), "pi_norm" or "pi_gamma" (pointwise prediction intervals), specifying which type of uncertainty bands should be plotted. Prediction intervals are either calculated summing the predicted mean variance and the residual variance ("pi_norm") or using 'posterior simulation' of the parameter vector ("pi_gamma") as outlined here: https://stat.ethz.ch/pipermail/r-help/2011-April/275632.html. Note that the "pi_norm" PIs are not generally applicable for generalized models. The posterior simulation approach is more generally applicable, but is currently only implemented for Gamma regression.
pi_alpha	If pi_type != "none", 1-pi_alpha% prediction intervals are plotted. Defaults to 0.05.
base_size	Base size of plot elements, see theme_bw. Defaults to 11.
xlab, ylab, main	Optional arguments for plot annotation
ybreaks, ylabels	Optional specification of the tick position and the corresponding labels (character vector) for the y axis
ylim	Optional y axis limits of plot
lwd	Optional line width. Defaults to 2
legend_symbol_size	Optional size of symbols in legend.
seed	Additional arguments passed to pi_gamma
