In carx: Censored Autoregressive Model with Exogenous Covariates

Description

Four diagnostic plots will be shown, which are

• the time series plot of the residuals,

• the residuals versus the fitted values,

• the ACF plot of the residuals, and

• the Ljung-Box test statistics versus the lags.

Usage

## S3 method for class 'carx'
tsdiag(object, gof.lag, col = "red", omit.initial = TRUE,
  mfrow = c(4, 1), main = "Diagnostic Plots from Simulated Residuals", ...)

Arguments

object	a carx object.
gof.lag	the maximum number of lags in ACF and Ljung-Box goodness-of-fit test.
col	color of some warning lines in the figures, default=red.
omit.initial	whether initial residuals should be omitted, default = TRUE.
mfrow	par parameter indicating how the plots are to be arranged, default = c(4,1).
main	The main title of the plot, default = "Diagnostic Plots".
...	Other arguments sent to plot.

Value

none.

Examples

dat = carxSim(nObs=100,seed=0)
mdl <- carx(y~X1+X2-1,data=dat, p=2, CI.compute = FALSE)
tsdiag(mdl)
