Exponential Q-Q Plot for SPQR / SPQRX Model

Source: R/SPQRX.R
eval.plot.qexp.Rd

Produces an exponential Q-Q plot using model-based CDF values. The function evaluates the fitted conditional distribution and compares transformed probabilities to the theoretical exponential distribution.

Usage

eval.plot.qexp(model, x, y, pre_normalize = FALSE)

Arguments

model

A fitted model object returned by fit_spqrx().

x

Matrix or data frame of covariates.

y

Numeric vector of observed response values.

pre_normalize

Logical. If FALSE (default), response values are normalized using stored model parameters.

Value

Invisibly returns NULL. Produces a base R Q-Q plot.
