plot.accuracy {gmGeostats}

Plot method for accuracy curves

Description

Plot an accuracy curve out of the outcome of accuracy().

Usage

## S3 method for class 'accuracy'
plot(
  x,
  xlim = c(0, 1),
  ylim = c(0, 1),
  xaxs = "i",
  yaxs = "i",
  type = "o",
  col = "red",
  asp = 1,
  xlab = "confidence",
  ylab = "coverage",
  pty = "s",
  main = "accuracy plot",
  colref = col[1],
  ...
)

Value

Nothing, called to plot the accuracy curve \{(p_i, \pi_i), i=1,2, \ldots, I\}, where \{p_i\} are a sequence of nominal confidence of prediction intervals and each \pi_i is the actual coverage of an interval with nominal confidence p_i.
