plot.maq {maq}

Plot the estimated Qini curve.

Description

Plot the estimated curve Q(B), B \in (0, B_{max}]. If the underlying estimated policy \pi_B entails treating zero units (that is, all the estimated treatment effects are negative) then this function returns an empty value.

Usage

## S3 method for class 'maq'
plot(
  x,
  ...,
  add = FALSE,
  horizontal.line = TRUE,
  ci.args = list(),
  grid.step = NULL
)

Arguments

x

A maq object.

...

Additional arguments passed to plot.

add

Whether to add to an already existing plot. Default is FALSE.

horizontal.line

Whether to draw a horizontal line where the Qini curve plateaus. Only applies if the maq object is fit with a maximum budget that is sufficient to treat all units that are expected to benefit. Default is TRUE.

ci.args

A list of optional arguments to lines() for drawing 95 % confidence bars. Set to NULL to ignore CIs.

grid.step

The spend grid increment size to plot the curve on. Default is max(floor(length(path.length) / 1000), 1) where path.length is the size of the grid underlying the estimated Qini curve.
