In gofreg: Bootstrap-Based Goodness-of-Fit Tests for Parametric Regression

Test Statistic for parametric regression models (abstract class)

Description

This is the abstract base class for test statistic objects like CondKolmY or MEP.

Test statistics are built around the key method calc_stat() which calculates the particular test statistic (and x-y-values that can be used to plot the underlying process).

Methods

Public methods

• TestStatistic$get_value()

• TestStatistic$calc_stat()

• TestStatistic$get_plot_xy()

• TestStatistic$print()

• TestStatistic$geom_ts_proc()

• TestStatistic$plot()

• TestStatistic$clone()

---

Method get_value()

Returns the value of the test statistic.

Usage

TestStatistic$get_value()

Returns

value of the test statistic

---

Method calc_stat()

Calculate the value of the test statistic for given data and a model to test for.

Usage

TestStatistic$calc_stat(data, model)

Arguments

data

list() containing the data

model

ParamRegrModel to test for

Returns

The modified object (self), allowing for method chaining.

---

Method get_plot_xy()

Returns vectors of x and y that can be used to plot the process corresponding to the test statistic.

Usage

TestStatistic$get_plot_xy()

Returns

list with plot.x and plot.y being vectors of the same length

---

Method print()

Overrides the print-method for objects of type TestStatistic to only print its value.

Usage

TestStatistic$print()

Returns

The object (self), allowing for method chaining.

---

Method geom_ts_proc()

Creates a line plot showing the underlying process of the test statistic.

Usage

TestStatistic$geom_ts_proc(...)

Arguments

...

Other arguments passed on to ggplot2::geom_line(). These are often aesthetics, used to set an aesthetic to a fixed value, like colour = "red" or size = 3.

Returns

A ggplot2 layer representing a line plot.

---

Method plot()

Creates a new ggplot showing the underlying process of the test statistic.

Usage

TestStatistic$plot(...)

Arguments

...

Other arguments passed on to ggplot2::geom_line(). These are often aesthetics, used to set an aesthetic to a fixed value, like colour = "red" or size = 3.

Returns

A ggplot2 object representing the complete plot, including a line geometry.

---

Method clone()

The objects of this class are cloneable with this method.

Usage

TestStatistic$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
