TracePlot function

Trace plot

TracePlot(
  fit,
  par,
  comp = 1,
  sel = NULL,
  main = "",
  xlab = "iteration",
  ylab = "parameter value",
  ...
)

Arguments

• fit: An object containing the results returned by a the kmbayes function
• par: which parameter to plot
• comp: which component of the parameter vector to plot
• sel: logical expression indicating samples to keep; defaults to keeping the second half of all samples
• main: title
• xlab: x axis label
• ylab: y axis label
• ...: other arguments to pass onto the plotting function

Returns

No return value, generates plot

Examples

## First generate dataset
set.seed(111)
dat <- SimData(n = 50, M = 4)
y <- dat$y
Z <- dat$Z
X <- dat$X

## Fit model with component-wise variable selection
## Using only 100 iterations to make example run quickly
## Typically should use a large number of iterations for inference
set.seed(111)
fitkm <- kmbayes(y = y, Z = Z, X = X, iter = 100, verbose = FALSE, varsel = TRUE)

TracePlot(fit = fitkm, par = "beta")
TracePlot(fit = fitkm, par = "sigsq.eps")
TracePlot(fit = fitkm, par = "r", comp = 1)
