residual_diag: Emulator Regression Residuals

In hmer: History Matching and Emulation Package

Emulator Regression Residuals

Description

Plots the emulator residuals.

Usage

residual_diag(emulator, histogram = FALSE, ...)

Arguments

emulator	The emulator to consider.
histogram	Should a histogram or a scatter plot be shown? Default: FALSE
...	Any additional arguments (used internally)

Details

An emulator is composed of two parts: a global regression surface, and a local correlation structure. It can sometimes be informative to examine the residuals of the regression surface on the training set, to determine the extent to which the regression surface is being ‘corrected for’ by the correlation structure.

Value

A set of residuals, standardised by the regression surface residual standard error.
