estimateEffects()
is used to estimate the effect of the
treatment along the entire frontier.
1 2 3 | estimateEffects(frontier.object, formula, prop.estimated = 1,
mod.dependence.formula, continuous.vars = NA,
seed = 1, means.as.cutpoints = FALSE)
|
frontier.object |
An object generated by |
formula |
An object of class formula (or one that can be
coerced to that class). This will be passed to
|
prop.estimated |
The proportion of points on the frontier to estimate. By default, 100% of the points on the frontier are estimated. To estimate less than 100% of the points, pass the proportion to be estimated to prop.estimated (for example, .6 to estimate 60% of the points). |
mod.dependence.formula |
The formula used as the base formula for the Athey-Imbens model dependence estimates. |
continuous.vars |
All continuous control variables in mod.dependence.formula must be passed as a character vector to continuous.vars. A cutpoint for each of these variables will be estimated with segmented regression. |
seed |
The seed used before estimation of the effects. If prop.estimated is less than 1, this is necessary in order to replicate the exact plot. |
means.as.cutpoints |
FALSE by default. If TRUE, cutpoints are calculated as the mean instead of the breakpoint in a segmented regression. This is sometimes much faster. |
