RBPcurve (version 1.3)

addWellCalib: Visualizes a measure for well calibration on the RBP curve.

Description

A measure for a well calibrated model can be obtained by grouping the predicted probabilities via deciles yielding 10 groups. The equally collored areas belong to a specific group. When each of the two equally collored areas are similar, the model is well calibrated.

Usage

addWellCalib(
  obj,
  plot.values = TRUE,
  subplot.control = list(diff = TRUE),
  col = shape::greycol(10L, interval = c(0.3, 1)),
  pos = NULL
)

Value

A matrix that contains the average of the “probabilities within deciles”

conditional on Y.

Arguments

obj

[RBPObj]
Data container for RBP curve.

plot.values

[logical(1)]
Whether the values of the corresponding measure should be added to the plot? Default is FALSE.

subplot.control

[list] A named list of arguments that will be passed to barplot. Additionally, you can set diff = TRUE to plot differences of the equally collored areas or diff = FALSE to directly plot the areas of the equally collored areas in juxtaposed bars.

col

[character | numeric]
A specification for the the plotting color for the areas.

pos

[list] A named List that determines the x and y positioning of a subplot that compares the areas in additional barplots (see subplot). Can be NA for no additional subplot. Default is pos = NULL for an auto positioning in the topleft quadrant.
