plot.ame: Plot a summary of FLAME or DAME

In FLAME: Interpretable Matching for Causal Inference

Description

Plot information about numbers of covariates matched on, CATE estimates, and covariate set dropping order after a call to FLAME or DAME.

Usage

## S3 method for class 'ame'
plot(x, which_plots = c(1, 2, 3, 4), ...)

Arguments

x	An object of class ame, returned by a call to FLAME or link{DAME}.
which_plots	A vector describing which plots should be displayed. See details.
...	Additional arguments to passed on to other methods.

Details

plot.ame displays four plots by default. The first contains information on the number of covariates that matched groups were formed on, and thereby gives some indication of the quality of matched groups across the matched data. The second plots matched group sizes against CATEs, which can be useful for determining whether higher quality matched groups yield different treatment effect estimates than lower quality ones. The third plots a density estimate of the estimated CATE distribution. The fourth displays a heatmap showing which covariates were dropped (shown in black) throughout the matching procedure.
